Re: Jennifer Lawrence/Mystique. Introducing this sexy and talented actress.
Beast and Mystique could share some words on the sequel, but taking into account each one is on a total different place and team, I dont see how Bryan would explore their relationship, at least a possible love one.
Each sequel should show Raven getting colder and more distant to both Hank and Charles. So if they make their relationships stronger, it would be more unbelievable to develop her into the killer Raven
