Now, I still think it would've made more sense for *RE5 SPOILERS* Wesker's henchwoman to be Sherry than Jill *END SPOILERS*
But, I do think the woman in this is Ashley. Looks and sounds too much like her. If it were Sherry, I don't see why they wouldn't have changed her look a bit. I mean, it would be ten years. How many women do you know who keep the same hairstyle they had when they were little girls?
