That could have been Ashley at the end of the Damnation trailer but I'm really doubtful. My point is that in the Resident Evil 6 trailer, it said President Adam Benford (or whatever) and Leon had been friends for years. If Damnation is a prequel, maybe Adam was still in presidency. Think about it---- in Resident Evil 4 the president of the U.S. was President Graham.Years passed and he probably didn't get relected cause of his annoying, high-pitched voice daughter.
If the voice wasn't Ashley then who could it be? And just because the US Pres. wasn't Ashley's dad anymore doesn't automatically mean that she won't be in the film... What if her Dad and the current president (Adam) had a fight or something and then Leon gets hooked up with the drama and all that since Adam is his friend and he had a relationship with Ashley, something like that etc lol.
I'm betting that voice is Ashley's simply because I don't have any idea whose it might be.
