a/n: I knew I'd kill a few brain cells with chapter three. If anyone has watched alternate reality stories on Star Trek or other shows, they come up with some very twisted technical reasons as to why it's happening. I had to follow sci-fi continuity!

Major bonus points to AkiSue for being the only one to mention the Quantum Leap/Supernatural reference at the end of the last chapter. I guess it's really hard to find people who have watched both shows.

Anyway, thanks so much for all your comments. Now, the conculsion.

--------------------------------------------

House and Arvin stood in the middle of the cafeteria, seeking metaphysical clues while getting the attention of nearby diners. "What sort of cracks in space/time can happen in a room like this?"

Arvin thought about it. "Spatial events can happen anywhere. Where's the morgue in relation to this room?"

"Down three floors, almost exactly."

He nodded. "For years general relativity predicted an area of space to follow a smooth flowing surface while quantum mechanics predicted a random, warped, surface. The superstring theory reconciles the two, replacing the classic idea of point particles with loops, with extremely small variances. Using that type of thinking, I can run through Planck calculations to get a measurement of natural units. I've already ran a few simple calculations off the top of my head, and I don't see how this can be the room where it happened."

"You can do Planck calculations off the top of your head? Man, you are a freak." House replied.

"Since we know the entrance point was the morgue, we should start there."

"House!" Cuddy shouted from afar.

House looked around full circle. "See any hyperspatial escape routes?"

Arvin shook his head as Cuddy made her way over. "Who's the geek?"

"He's here for a consult," House answered.

"So this is how you manage to avoid talking with the police about Chase and Cameron's disappearance?"

"Oh, we're working on that," Arvin said enthusiastically. "You see, all we need to do is find the proper string-"

House cut him off. "He's suffering from dementia. Got to give him that MRI now."

Cuddy gazed at him with indignation. "I'm watching you House. You better be cooperative."

"No sweat, gotta go." He pulled Arvin along. "When we're done here, we need to work on ways to make her disappear."

----------------------------------------------

After twenty minutes of searching through the halls, Francine heard pounding behind a closet door. "Let me out!"

"In here Dr. Wilson," she said, leading him over. Wilson opened the door. He freaked out when he saw Cameron there.

"You can see her?" Angie asked, very surprised.

"What, you can't?"

She shook her head.

"Why can I?"

She shrugged, at a loss for a reason.

Wilson went back to Cameron. "Are you okay?" He tried to grab Cameron's hand, but his grasp slid through it. He felt like he was going to pass out and started hyperventilating.

"What's the matter?" Cameron and Angie both asked, reaching to help him.

"I thought House was pulling a prank. Your disappearance, it's actually real." Cameron and Angie both held back huge smiles while giving him time to pull himself together. Cameron wondered why she felt like laughing since Chase was right, Wilson didn't believe them and was playing along. Now she owed him a hundred bucks.

Wilson looked behind Cameron into the closet when he started to calm down. "Where's Chase?"

"I don't know. The horny spirit tossed me in the closet and then took off with him. Bitch."

Wilson pinched the bridge of his nose. "I really don't know how this can get any weirder." He realized he spoke too soon when House and Arvin tiptoed slowly by, eyes fixed forward, the young physicist holding something electronic in his hand while punching all sorts of buttons.

"Come on," he said taking Francine's hand and waving Cameron and Angie along. "We need to find Chase."

------------------------------------------------------

Chase figured he only had one option. He was going to have to rationalize himself out of this irrational situation. He was dragged into a hospital room, on the third floor he concluded, and tied to the chair with a set of body restraints. He kept feeling himself touched all over, at random times, not to mention kissed. He was getting disturbed.

"Hey, um, Miss Ghost, I'm flattered by all the attention, but you need to let me go."

There was no answer. Apparently this wasn't a very talkative ghost. "I'm not who you want. I'll never make you happy. I'm pretty serious with my girlfriend, and I can't be a doctor in this world and help people."

Still no answer, but he felt his pants being unfastened. He struggled, to no avail. "You don't want to do this. You deserve someone who's willing."

There was a pause, and no further action on his zipper. He took in a sigh of relief. He needed to keep talking like that.

"I'm sure you'll find someone wonderful in your life just like I did with Allison."

Wrong thing to say. Now something was digging at the band of his underwear.

"Not that I don't think you're pretty. In my mind, I imagine you're quite a looker." The tugging stopped, and a faint image appeared in front of him. Beyond her ethereal appearance, Chase saw the flowing blonde curly hair, and deep blue eyes. He smiled. "You're beautiful."

She smiled back, and her long pause made him think she was considering everything he said.

"You don't want to hurt me. I think you're better than that."

She smiled again and reached for a restraint on the back of the chair when they heard familiar voices come from far away. Chase opened his mouth to alert them, but something was stuffed in it instead. The ghost disappeared.

Chase's muffled cries went unheard as Cameron and Wilson's voices faded beyond the room.

----------------------------------------------------

Cameron was frantic. They had been searching for an hour, and they were no closer to finding Chase. "We have to find him. I'm not leaving without him. Plus there's no telling what that she-devil must be putting him through."

"There aren't too many places left to look," Wilson said, trying to assure her. "We're just going to have to check every room."

"That'll take so long!" Cameron said. "We might not have that kind of time."

Francine stopped in her tracks.

"What is it?" Cameron asked.

"Shh, I think I hear something." She listened carefully. All of a sudden, they heard a loud crash. Everyone except Angie that is.

"You didn't hear that?" Wilson asked.

"Hear what?" Angie replied.

Cameron's eyes grew real wide. "He's in there!" She led the group into the hospital room. She slid open the door to find a patient asleep in the bed, and Chase tethered to a chair that had fallen onto the floor, crashing the contents of a tray table with it.

Cameron rushed over to him and pulled away a roll of gauze that was in his mouth. "Robert, are you okay?"

"This so never happened in Star Trek," Chase said. He noticed Wilson looking at him in fascination. "Wait how can he-?"

"We don't have time to figure it out right now. House and the weirdo are getting close. We've got to hurry."

Just then Cameron felt herself kicked in the side, and skidded backward a good way across the floor. She felt a punch to the jaw next. "That does it!" She declared, bolting up in defiance. "You and me, Sheila. Winner takes all."

A faint apparition appeared in front of her, laughing over such a ludicrous idea. Cameron ran forward, running completely through her. She propelled forward and the creature kicked her from behind.

"Do you see the ghost?" Wilson asked Francine.

Francine shook her head. "He does though." She pointed to Chase, still bound to the chair, trying his best not to look amused over two women fighting over him. A smirk slipped by once in a while though. Wilson tried not to laugh himself over this strange cat fight.

Cameron got up, the look of determination in her eyes. This bitch was toast. "I bet you can't take my quantum foam!" She threw a blast of energy from her hands, and the ghost went flying. Chase, Wilson and Francine's eyes met with a stunned look, all wondering where the hell that came from.

The ghost disappeared, and Cameron jumped out of the way just in time as it made another surge. Cameron threw another energy pulse, and the ghost's figure appeared before going through the wall.

Cameron got up, and untied Chase. He grabbed her in a hug. "How did you manage to do that?"

"I honestly don't know."

A loud creepy groan came from the walls, the lights flickered and the room began to shake. "I remember now!" Cameron exclaimed. "We ducked into this room for a little private time. That's when everything began shaking."

"I remember too," Chase said, a nervous tone to his voice. "Something flung us forward and –" Within an instant, they were gone. The room returned to normal, leaving Francine clutching onto Wilson for dear life.

"Where'd they go?" Francine asked Wilson.

"I have no idea." Wilson replied.

"Wait a second, you're telling me that they just disappeared with the ghost?" Angie asked.

Francine and Wilson both nodded in disbelief themselves.

It all started making sense to her as she paced around a bit. "The ghost must have found a doorway, and pulled them in." Her eyes jumped out of their sockets. "The morgue! That's the other side."

The patient woke up, Angie's loud voice finally being the sound to wake her. She was shocked over the sight of the three stunned strangers in her room. "Did I miss something? You three look like you've just seen a ghost."

"Sorry ma'am. Wrong room." Wilson said apologetically. They hurried out of there, headed straight for the morgue.

---------------------------------------------------

His head hurt like hell, throbbing hard at the top of his skull. His hands were flat on the cool linoleum, the hardness beneath him adding to the evidence that he was on the floor. Something wasn't right.

Chase tried like mad to remember what happened, but it was all blank. He opened his eyes, and sat up in shock to see he was on the floor in the morgue. His sudden movement exacerbated his headache, causing him to cry out in pain. They weren't close to the morgue earlier, so he wondered what practical joker put him there. Someone had to have drugged him.

His head turned to the floor space next to him, where Cameron's motionless body laid a few feet away. He frantically crawled to her, wincing at another sudden rush of pain to his head. He felt for a pulse and found a strong one, exhaling in deep relief. He gave her a shake. "Allison, please, wake up."

Her eyes cracked slightly open, her dazed look telling him she still wasn't all there.

"It's okay, take your time. You're fine." He assured, clutching her hand.

"Wha…what happened?" Her weak voice asked, barely managing to get the words out.

"That was awesome!" They heard coming from the other side of the room. They glanced over to see the geek, holding something in his hand, while House stood next to him, white as a sheet, looking as if he had just seen, well, ghosts.

"My instruments were flying off the chart, and now nothing. You managed to make it through another crack in space/time. My calculations had it happening exactly where you are now. I'm so going to get published for this!"

"Glad we could help, Arvin." Chase said before falling backward onto the floor in exhaustion.

"Don't you have anything to say House?" Cameron asked, surprised by his inability to speak. That had to be a first.

"I never thought it was real. I thought Wilson was playing a joke."

Chase and Cameron started rolling on the floor, laughing. After all they had been through, they couldn't avoid feeling a little slap happy on top of everything else.

"The police, the cancer kid, the parapsychologist, it was all a perfect touch. So Wilson."

Wilson, Francine, and Angie entered. Francine ran over to Chase and Cameron and fell on top of them, giving them a huge hug. "You're back!"

"How did they end up here?" Wilson asked the genius.

"Once again, they were in the right place at the exact right time. An energy fluctuation and then bam! I got it all recorded."

Angie's interest spiked. "Really, you actually recorded energy fluctuations?"

Arvin nodded.

Angie started talking excitedly. "Dr. Cameron was able to throw energy upstairs in a hospital room while part of the other realm. I bet the spirit is in another universe, knows everything about the energy rift and has the knowledge to move people through it and all the universes that touch it. The fluctuations were due to her movements in and out of time."

Arvin was on the same wavelength. "She could throw energy because the quantum foam expanded in that room. More particles were charged, causing all sorts of changes in energy and superstring frequencies."

"That's why Dr. Wilson could see Cameron and Chase after he couldn't see them before," Angie theorized. "The waves stirred by the ghost phased the surrounding energy to a frequency his perceptions could understand. Come with me. One of the PEAR labs hasn't been dismantled yet. We need to analyze this data now!"

Arvin followed her enthusiastically.

"Oh, Dr. Wilson," Angie said, stopping in front of him. "We'll need to thoroughly examine your brain."

Wilson looked less than enthused by the idea when they both rushed out, leaving the others behind to picture what could happen when a parapsychologist and quantum physicist were holed up in a small room together for a long period of time. It boggled the mind.

"Every wonder how many parapsychologists and quantum physicists it takes to screw in a light bulb?" Chase joked.

Cameron almost smacked him on the back of the head, but stopped herself.

After all they'd been through, she would permit one bad joke. She got up and helped Chase and Francine up as well. "Let's never dress up for Halloween again. I don't ever want to be stuck in another world with a ridiculous outfit."

"I'm never watching Star Trek, The X Files, Supernatural, Stargate SG1, Dr. Who, Torchwood, or even Quantum Leap again either," Chase said. "They have no idea what they're talking about."

They all headed out of the room, except for a stunned House, who was frozen in his tracks. "Coming, House?" Wilson asked.

House still couldn't mutter a word. His mind was trying to reconcile how all of this could even be possible. It had no reason.

Chase walked over and patted him on the shoulder. "I've had a perspective change, House. This experience was worth it just to see the look on your face right now. All is forgiven." House still didn't move as everyone left.

---------------------------------------------

Chase and Cameron stumbled through her front door, completely exhausted, before dropping onto the couch. They had just spent the last few hours with Cuddy and the police making up some story about how they were trapped in the morgue for the last sixteen hours. The police didn't believe them at first, but it was the most rational explanation they were ever going to get. The truth couldn't be fathomed.

"I'm sorry, but I have to ask. What did that ghost do to you?" Cameron asked suspiciously. "She had you to herself a good long time."

"She tortured me, what do you think?" Chase said, offended by her tone.

"Did you get it on with her? What is sex with a spirit like?"

"Nothing happened, although if something did, I had no choice."

"I bet you liked it."

"I'm not discussing this with you."

"Aw, poor baby."

Before he could defend himself further, she silenced him with a huge kiss. "If any good has come out of this experience, it's convinced me that together we could handle anything."

Chase laughed. "I loved how you fought for me. I think that was why she decided to send us back. I could never be hers."

Cameron stretched out and rested her head on his chest. It felt so good to be home. "You think we'll run into her again?"

"Maybe. If we do, we should try and find her a he ghost."

Cameron smiled. "Let's save that adventure for next Halloween."
