If it is jill, then where on earth was she in the past years??? Was she captured by Wesker? But the gravestone scene may be saying she died. I know RE Universe boast extreme biotech, cloning is a great possibility. But if its jill, then the clone would only be a couple of years old, she could not be an adult by the time of the game (unless capcom decided to give wesker the knowledge to produce a fully grown clone, highly unlikely). I stand by my grounds that the bird lady is Sherry, this i think will also lead to tying up knots from the past. Remember that Sherry is waiting for Claire, which may be a basis for RE6 (hopefully)
