Sam had no idea where he was or what he was doing. Last thing he remembered was Cas reaching into his head and now he was at some bar that he didn't recognize. He kept seeing little flashes in his head of you and Dean, giving him the tiniest bit of information. But he still couldn't figure out how to get to you, and he was getting panicky.
"C..can you help me?"
He swallows hard as he asks the bartender, trying to keep himself together.
"Yeah sure, what's up?"
She asks him, looking all too friendly.
"I don't know where I am. I…I can't remember anything."
Sam blinks, seeing a violently painful rush of Lucifer. He doubles over, sitting on the floor and cowering under the bar stools. This was starting to hurt.
"Please.."
He whimpers, feeling his throat burn.
"I want My Persona. I want…I want My Persona."
Sam begs to no one in particular as he makes himself smaller on the floor, his head falling into his knees. Little did he know, you were right there. Holding his unconscious body at Bobby's house while he was trapped inside his own mind.
