Re: Jean Grey in The Wolverine
Every film after X3 had a cameo from the original cast, so this is nothing new. Professor X for Origins: Wolverine, Wolverine for First Class and now for this movie, its Jean Grey. Its probably something that isn't super related to the main plot of the movie but if it might be a connected to DOFP.
