...I don't recall hearing of ANYONE that thought she was ANYTHING like Birkin's version of the Wesker Children.
And no, despite how bad Capcom is at handling ANY story, in the hands of the fans it'd be even worse since most the time they'd be doing things just for simple fanservice and never being able to decide amongst themselves where the actual story should go or what should be the focus.

No I said she "might" be Birkin's own version of Wesker's Children.
Fans on the other hand has many times said she could be a creation of Birkin rather then daughter of of his flesh and blood sense.
I still think that many things fans offered in the way of plots could have offered more too the series then Capcom themself.
But I will have to wait and see if RE6 is now the so called reboot as some say perhaps,perhaps they will give us a plot that is descent to creater further titles on, minus the thousened of plotholes,forgotten characters etc this time.
