Hank/Jean
I became like I was after trying a cure that I developed from Raven's cellular material. I don't know if it's any consolation or indication, but those changes were near immediate and I've been more or less stable for two weeks now.
But, I can't say I know either. No one's ever mentioned any experiments done by other Hanks (can one pluralize their own name, I wonder? Curious). But Logan and Scott have implied there were some.
