These are also the franchises that can't leave well enough alone when it comes to continuity and Alien media has certainly gone to the well with Acheron. So Vickers could be alive here, but then again it's fairly far fetched. Then again so is Hadley's hope surviving a nuclear blast intact. I don't know maybe she crawled out and puffed herself back up like a cartoon, I don't know.
I don't think it's Vickers either I'm just waiting for a new creative team.
