Sam chanced an anxious glance over his shoulder. It was irritating that he had to face off with Bobby right now - or even at all, because frankly Sam would easily prefer avoiding him at all costs at the time being - especially when he was supposed to be off finishing this hunt for Lilith. Did he and Dean realize the severity of the situation at all? Lilith was close. If they didn't find her now, then they were going to be screwed in every way possible. Damn the consequences on his part; there were worse things in the world than Sam drinking demon blood, particularly when one had the apocalypse and Lilith to compare to. Sam looked back to Bobby and shook his head, hands hanging loosely at his sides. "You know where I'm going. I can't stay here anymore, Bobby. She's getting close and you and I both know that we're gonna lose this thing if I don't find her."
He'd have liked to do this thing together. Him, Dean, Bobby, and Ruby. But would they be able to accept the extremes that Sam was going to have to take to get the job done? No. Not Dean, at least. Sam knew his brother. He'd have just as well sat by and watched the world burn than do the same with his own blood. Sam furrowed his brow. "I don't want to fight with you guys. You know that. So do us both a favor here and let me go, Bobby. I have to do this." If Bobby didn't let him walk, they both knew how this was going to end. Sam knew that they were as frustrated with this situation as he was, but there was no way in hell he was going back in that panic room ever again.
