You, a mutant, a powerful one, agreed to join Wolverine in his journey to destroy Stryker and his brother, and came with him to the casino to find the one escapee of Trask's island, and the only one who would know where the island was. You watched the back door for Logan(Wolverine), but it didn't take long for him to get thrown threw the wall by Remy. The Gambit thought Wolverine was one of Stryker's guys, and was trying to bring him back too the island to be experimented on.

And the Cajun came running out after him, ready to fight.

"I'm not going back!"
