Set immediately after 4.22

"What's he doing down here, Bobby?"

"Don't know. He told me I should lock the door and that's when I came and woke you."

Dean and Bobby were standing at the bottom of Bobby's basement stairs, talking in low tones. Sam was sitting on the cot in the panic room, his back turned to them.

"What happened last night, Dean?"

Dean let his mind go back to the events of the previous night. He'd practically dragged his little brother from the convent. Sam had frozen at the sight of Lucifer starting to rise.

Somehow the Impala had been there. Dean didn't question it. He'd jumped in, waiting for Sam but Sam had frozen again. This time he'd been staring at Ruby's car with tears in his eyes. Dean forced his brother into the Impala, lit a book of matches and tossed them into the open window of the little orange car. The explosion rent the night as they made their getaway.

Sam had been too quiet on the frantic drive to Bobby's. He'd stared out the car window, silent tears coursing down his cheeks. Even though Dean had really needed both hands to drive as fast as he was going, he'd kept one hand on his brother's arm, just so Sam would know that he was there and everything was going to be okay.

Dean shrugged. "Long story short? He killed Lilith, we killed Ruby, Lucifer starting rising, we got the hell out of dodge."

Sam had fallen asleep as soon as they arrived at Bobby's. Dean had helped Bobby angel/demon proof the place and then spent the rest of the night dozing in a chair beside Sam's bed.

Dean hated putting Bobby in the middle of it but they had nowhere else to go. He had no doubt they were on Heaven and Hell's most wanted list. Somehow that didn't scare him nearly as much as seeing Sam in the panic room once again.

"Be easy on him, Dean."

Dean swallowed thickly. "I just got my brother back, Bobby. I'm not going to push him away again."

Bobby nodded. "I'll be upstairs if you need me."

Dean took a deep breath and headed toward the room that held so many unpleasant memories.

"Hey, Sammy." Dean sat down beside his brother. "What are you doing in here?"

"You should get out." Sam's voice lacked any emotion. "And lock the door behind you."

"Sammy, what is this about? Is it about last night? You didn't know that Lilith was the last seal. It's over, it's done with. We have to regroup and figure this out but beating yourself up over it isn't going to change anything."

Dean winced as he said the words. Was that being easy on Sam? Considering that Dean still wanted to punch Sam's lights out for leaving him on the floor of that hotel and for believing Ruby over his own brother, yeah, he thought it was being pretty easy.

"That's not all I did last night, Dean."

"What are you talking about?"

"The demon blood…..I had to….I…oh, God, Dean." Sam lowered his head into his hands and moaned softly.

"Sammy, I already know about the demon blood."

"You don't know everything."

"It doesn't matter, Sammy." Dean rested his hand on his brother's back. "Everything is going be okay, I promise."

"How? How is it going to be okay?" Sam jumped up from the cot and began pacing frantically around the room. "I'm a blood sucking freak. You said so yourself."

"What?" Dean gave Sam an incredulous look. "I never said that."

"You left me a message. You said you were going to hunt me."

"Sam, I never said that." Dean's jaw clenched as he fought to keep his emotions in check. "I called you to say I was sorry. That's all, I swear."

"But the message…you said….."

"It was the angels or the demons manipulating us again. Zachariah said he was going to make sure you got the nudge you needed. Was that it?"

Dean's heart twisted at the crestfallen look on Sam's face. The phone message had been the final straw to push Sam over the edge. Even though Dean hadn't left the message that Sam heard, he still felt like it was his fault.

"Sam, I'm…." Dean never finished the sentence.

Sam's eyes rolled up in his head and he fell to the floor, convulsions racking his body.

Dean was on his knees, trying to keep his brother from hurting himself. It was too déjà vu. "Bobby!" he screamed. "Help me!"
