Where was Julian when the big battle went down? We hope he was tied up in the lab, desperately working on a way to help Caitlin. But judging from the look on his face, it doesn't appear things are going well.
One mystery I cannot figure out is why some people come into our lives and why some people go. Others become a part of you.
