McGee hadn't been able to get back to sleep after his visit from Castiel. The angel had left abruptly, making Tim wonder if it had all just been some weird waking-dream. But it had left him unsettled enough to stay awake. 0430 wasn't an unheard of time to get up, anyway.

Luckily, he'd brought his laptop downstairs before giving Ducky the room and he was able to kill time till sunrise, writing out his strange dream with Castiel, and playing Red Cell with people who'd undoubtedly not even gone to bed yet. It was 0500 when Ziva quietly came downstairs in sweats and told him she was going for a run. He told her to be careful, and she'd merely given him a smirk before heading out the door.

When he realized the sun had come up behind him, he shut down the game and made his way into the kitchen to start a pot of coffee. As he filled the carafe with water, he wondered why no one had thought to bring a second machine over by now. The twelve-cup brew would satisfy Gibbs, but what about the rest of them?

"Morning," he heard Tony greet from the doorway, and he turned to see the slightly disheveled-looking agent.

"Hey, Tony," he grinned, happy to see him looking ten times better than the night before. "You're up early."

"Was about to say the same to you," he said as he shuffled further into the room. "Ziva brought a thermos," he motioned to the top of the fridge where the silver container sat. "So you can dump that pot into it when it's done and start some coffee for the rest of us," he smirked. Tim couldn't help but let out a small laugh at the ironic solution to his previous thought. "Sorry about...slightly freakin' out last night, Probie," he grimaced.

The smile left Tim's face and he furrowed a brow. "I don't blame you for freaking out, Tony. That was...a lot to process."

"It's just that...I was so focused on the promise I made to Dean, to watch out for his little brother, that I kinda got sidetracked from watchin' out for my own." Until that moment, Tony's eyes had been focused elsewhere. But now the green orbs met with the possibly shocked or amazed, hazel eyes of the younger agent.

"Did you just-"

"Yeah, I did," Tony didn't wait for the full-out question. Tony had essentially called him his little brother, and it was the nicest thing McGee could remember him ever having said to him. "Figured a thing or two I wished I woulda said, when I thought you weren't coming back. I'm sorry I didn't have your six, Tim."

"Tony, you couldn't have stopped it-"

"Fact is, you died," he interrupted yet again. "I let you down."

"No, you didn't. You saved me in the end. Even if you didn't know you were doing it. I'm right here. I'm alive, and it's because of a decision that you made." Tony looked at him, thoughtfully, for a good long moment. "Oh god...you're not gonna hug me again, are you?" McGee grimaced.

"Think I'm gonna have to," Tony blurted out, "Just a little." He wrapped his arms unceremoniously around McGee and hugged him.

"You done gropin' McGee so I can come in there, DiNozzo?" Gibbs' voice sounded from the doorway.

"Go 'way, boss," Tony mumbled, his words slightly muffled by the way his face was shmooshed against Tim's shoulder. "Coffee's not ready yet, anyway. Besides, McGoo likes it," he grinned when Tim pushed him away.

"Real funny, Tony," he grumbled before turning to open the fridge.

"Don't make me call Vance and order up another harassment seminar," Gibbs said as he entered the kitchen.

"You wouldn't do that, boss," Tony grinned. "'Cause then you'd be stuck attending it, too."

"Glad to see you're feelin' better this mornin'," Gibbs smirked as he poured himself a cup of coffee right as it finished brewing. "Thanks for makin' coffee, McGee."

"No problem, boss," Tim replied. "I'm gonna go grab my bag from the car so I can grab a quick shower before work."

"Hey, can ya grab my phone outta my car for me?" Tony asked. "I left it charging; should be in the front seat."

"Sure," McGee headed out just as Ziva made her way in the door. "Good run?"

"Most uneventful," she reassured him as she brushed past him toward the kitchen. "Good morning, Gibbs; Tony," she greeted as she went to the fridge for a bottle of water. She turned to appraise Tony as she opened the lid. "You are looking much better," she told him.

"Gee, thanks," he replied sarcastically, but with a smirk. "You don't look so bad yourself, being the first man down last night. Er...woman," he corrected himself. "I'd've thought you woulda been the one kickin' the most demon-butt."

"Well, I would have," she defended, "Had I not...hesitated. It was my mistake."

"Hey, well don't beat yourself up," Tony said as he sat at the table. "You did manage to ice one of those things before getting flicked across the room like a cigarette butt."

"I should've covered ya better," Gibbs added. "I'll admit, I thought it'd be like any other combat situation. Just with different weapons. But it wasn't, and that's where I made my mistake; tryin' to comprehend what we were lookin' at."

"Yeah," Tony agreed, "When Sam said it'd go down fast, he meant it." Small flashes of memory from the night before, came into his thoughts. He narrowed his eyes and looked up from the table-top where he'd be absentmindedly focused, and peered past Gibbs into the living room. "Wonder if he's having trouble gettin' into my car." He stood and made his way toward the front door.

When he opened the door, he immediately knew something was wrong. Amongst the parked cars in the driveway, his door was open and Tim's bag was on the ground. But McGee was no where in sight. "McGee?" Tony called out, walking up to the cars. "Probie, where are you?" his heart started pounding in his chest and he was only minutely aware that his voice was getting louder as he continued. "McGee?" he wove around each of the cars, peering inside each one.

"What's going on?" Sam's voice was suddenly behind him, and Tony realized then that Gibbs and Ziva had joined the search and Sam and Dean must have been woken up by his yelling.

Dean stepped in front of Tony and grabbed his biceps to stop him and get his attention long enough to repeat the question, "Dude, what's going on? What happened?"

Tony's eyes met his, fear and guilt displayed clearly for the hunter before him. "McGee's gone..."
