I found this info on a site like Wiki, that's for Resident Evil, and this is what it says about her.
(I'm still hopeing that it's wrong and shes Sherry!) ^-^



Allyson arrived in Kijuju around November time with her boyfriend. There, she met Adam; a miner. During a "date," a man in sunglasses was complaining in the bar over foreigners living in the region, and that the Kijuju natives must drive out the "invaders". His views led to a bar fight in which Adam and Allyson escaped and hid. The next morning, Allyson told Adam that she would be leaving with her boyfriend.

While Kijuju began to shift into madness and Adam began to ostracize himself within his home Allyson returned to him again. Sleepless and fearful of the situation that had presented itself and unable to find her boyfriend she takes up residence with Adam, much to his pleasure.

edit Role Allyson's role had been a mystery stemming from her first appearance in an early image of Chris holding her body as she lean weakened against him. It was highly speculated on her actual role, many believing her to be Sherry from Resident Evil 2. She made her trailer debut in the Leipzig trailer for Resident Evil 5 for a few seconds busting through a door and slamming into the building's railings which are holding her up. On the Resident Evil 5 TriCell Trailer she is seen again screaming for help and reaching out to Chris and Sheva. It was revealed in a recent German publication that her role is simply used to introduce the further Majini mutation having the parasite emerge from her face and attacking the two in a mini-boss event.[2] She has but one scene and is referred to as 'WIFE' within the games code, it is likely her role was expanded within Adam's blog to make her inevitable mutation much more tragic.



(What do you all think? by the way, Theres some kind of Blog on a Official Resident Evil Site, It's supposed to be this Adam guys Blog, and he talks about the girl in the red dress.)

I don't really know what to think, I had originally thought that Red Dress was Sherry, but now I am not sure....

If this came from a site like Wiki then it might not be the truth...I'm just waiting until the game gets here

Well I just dug up this thread that's got to be over a year old.

Anyway, looking back at this, after playing RE5.....a real shame.

I certainly don't recall anything even possibly explaining who the chick in the red dress was(that's right, back then, we all referred to her as the girl in the red dress(because it looked red, though I can admit it looks totally black in Mercs Reunion)), but her role was just seemingly unecessary, there's no point to having an american sounding character, with blonde hair and a red dress for no reason....it's something that seems like it's going to be hugely significant, and important, and it's just nothing.

Anyway, perhaps I missed a document in the game, anybody recall anything about this Allyson?

I don't know why it bugs everybody. I was just like oh well.

I still don't know yet if its true until now. I really hope that sherry is the blonde girl in RE6. Cause i want her alive and breathing lol.

Hmmmm, very interesting.

Well, shes a superstar now. Everyone think that she is God damn Sherry, Well, I dont think so dude.

Well I could have sworn she was Ashley because of the voice. That is impossible because the voice actress won't be on RE6 nad because her eyes color. Now I think is Sherry, and then is this about Allyson....Why can't RE6 come out on the 20th and Orc in november????
