Somehow Annie suspects that Sarah has some kind of connection with Jason but she wanted to be sure she was not mistaking and so wanted to have a proper investigations on the matter. She was even more interested in Sarah's case than Lilly was because her friend Lilly was already believing that her story may just have been similar to that of Jason Bourne just as the story of two people may seem fair and never correlate... So, Lilly was not ready to take things too serious when she is just meeting Sarah and have not had a close bond of friendship with her, and if she should begin to ask her questions and tell her there is a guy like Jason, ...what if she was mistaking and they are not really related to each other the way she felt? ...that may end up being abusive to ones feeling and may be derogating...
"Yes, I am." Sarah replied.
