Sam had been freaking out the moment he saw Jessica post on the network. She died in front of him.. or maybe that was never Jess and it was just planted inside his head? This was creeping him out. He had to go and see for himself that she was actually here.
Walking to where she worked since he needed the air he told Dean that he'd be back in a little while. He had to do something. He was still weak but Castiel was trying to help him the best that he could.
He walked inside the Purrfect Cup and tried not to cry in front of her. When she died it was devastating for him and here she was in the flesh. How long had she actually been here? He couldn't help himself as he walked to her and wrapped his arms tightly around her like he used to do. "Hey.." he said quietly back to her this was all strange to him but he was really happy that she was here with him.
