I'm still amazed at all the theory flaming/sarcasm that goes on, even though this is supposed to be a place to discuss theories in a mature fashion.
No, I don't think that Serge fighting his girl's uncle, whom he has nearly no memory of, merits the drama that it gets in the game, if that's all he really is. Maybe a little sadness that Miguel has to fight against the boy he essentially lost the rest of his life trying to save, but from Serge's side? I wouldn't feel all too sad.
Ok, so maybe Leena being the daughter of CT's heroes becoming friends with the main character of Cross is a bit stretched, but it's not as if she was a big character in this game. If I was fanficcing this idea, wouldn't I cast her, whom I thought to be the daughter of two of the biggest characters from CT, as a bigger role? Anyways, it's just a theory that has some merits and some flaws. Like many here made, it's not perfect.
And come on, the fanfiction comment was uncalled for. If you really want to laugh at this theory, talk to the ones who played a part in its creation.
