Isaac felt terrible about it, but if he could go his entire life without seeing anyone from Beacon Hills again, he would be fine with it. It wasn't because he disliked any of them, that wasn't the case at all, but seeing them just reminded him of everything. The confusing transition of the bite on top of the loss of his father and then Allison, it cut him too deep. If it was Scott, he wasn't sure if he would be able to do this. He cared about him, Scott took him in when no one else would, but Isaac still heard Allison's last words in his head, spoken to Scott with a tender sort of love that she had never used with him. She hadn't even looked at him.

He opened it and when he saw her, things came flooding back. The pack, that night, all of it. She looked the exact same, and for some reason, that was comforting to Isaac. He reached out for her and embraced her tightly in a hug before saying anything, squeezing her firmly before releasing her and moving aside.
