Hmmm.... That is odd, Must have been when someone posts false information, just caught me by surprise that is all. What I read went something like "Her father was originally thought to be Eli Vance, but has sinced change since HL2:Ep. 1" or something like that, probably just someone with false information, or a joke.
On a side note, I find it interesting that they don't mention her nude model they made as skin, nothing really important, it just struck me odd (mostly because of a YTMND fad, with a show called lazy town, and I looked it up on there, and they mentioned how the show's main character was a sex icon, for whatever reasons(don't ask...)
