Well, I've been listening to Wolverine: The Lost Trail, because it has Gambit in it. They have erred on the side of smarmy with his character. Though since Wolverine is portrayed as murderously unhinged, it shouldn't have surprised me that they would magnify negative character traits for everyone.
It could be a long con with Remy making it seem that there is a huge wedge between he and Logan, in case they are under surveillance and taking everyone by surprise when he shows up to help in the finale but >.>
