Re: Jean Grey in The Wolverine
I re-read it. It does sound a bit ambiguous. They mention the rumour is that it may be that Wolverine remembers a forgotten memory and suggests it's linked to the Jean Grey cameo. Needless to say I'm not a fan of that idea.
I don't mind Jean Grey having a cameo, but I'd rather it be a tie-in to DoFP and not something that leaves X3 as the last word on her character but at the same time goes against the earlier movies.
