Yeah, it would be nice if they got back together. But they both had some big issues and never got a chance to work them out!
My thought is that Leo was taken by the hysteria and his problems where greatly exaggerated!
That was truly sad that they might never speak to or see each other again when they where once such good friends! I have real life experience in that the person who was my childhood best friend I have not spoken to in 15 years! I mean if Leo and Chase decided to stay aprt for a while to heal, that would be good. But the possible goodbye forever is just too sad!
