Too old. Victorias son is 36 years old as he was born when she was 16, a year after her mother threw her out for a 30 year marriage to Maxwell which ended in 2006 when he died. + 6 years for it now being fall 2012 making her 51.
I think Victoria's firstborn son is Falcon, to be honest. They'd not have just mentioned him, right before we got to know about Victoria's child. On the other hand, it could still be Aiden. Authors wouldn't have said that he lost his mother without a particular reason, I think. Coleen was older than him, The Initiative knew about him, Helen asked him to kill Victoria, he can't stand Daniel, and to be fair, we know basically nothing for sure about Aiden. I know he's a bit too young, unless he lied about his age. It wouldn't be the first time when he lied. Besides, he still seems to be hiding something... Or maybe it's just me and my...odd feelings ;)
I don't think they would make someone an important character only to kill him before everyone realizes. Besides, in the finale last night, Victoria recognized her supposed "son" immediately, so other than the fact that Trask is dead, Victoria did not react that way when he saw Trask.
Ha. I suppose once they start releasing casting info, we can start guessing which of the new male actors will be Patrick. :D
