I'd have thought that Wolverine would have been able to tell it wasn't Jean in his tent by smell alone. That would have made a bit more sense than Mystique getting some scars that show up no matter how she looks (assuming she wasn't just trying to tell him who she really was.)
Why didn't Methos sound like Methos?
Didn't they have somebody else playing Pyro in the first movie?
I didn't see Stan Lee in this one but I my have just blinked at the wrong time.
