Again, it's completely obvious, but it could play into Allison's character... she's always been portrayed as a character that does not pay attention to detail and is not good at solving puzzles... it's why it's always the other characters that solve the situations, and Allison is simply around caught in the motions not knowing what is going on around her.Originally Posted by shinta|hikari
It's clear that she should know since it's obvious, but we have yet to see them interact with each other so the window is still open for the writers to make it so, as it wouldn't be out of character as obvious as it may be for us the viewers.
First we don't know how long it has been since they reconnected. Clark Kent anyone? Remember when Fi dressed up as a photographer how no one recognized her? Again, not uncharacteristic if they make Allison not recognize Wil no matter how improbable it seems... heck, some people here didn't notice. It's no use arguing it because aside from it being obvious to the viewers, that the possibility of it being so is still there, makes the question legit.
