A Kiss Before Dying Sabretooth is free of Tribune and must kill Mystique, but is after Birdy first for betraying him. Sabretooth returns to his mansion just as Birdy is trying to escape in his car. Sabretooth breaks a wall and grabs his secret motorcycle. Birdy runs overs Sabretooth only to hop in the car. The car hits the rail and they go over the bridge.
Sabretooth makes Birdy go into his head to learn about Tribune.
Later, Birdy helps Sabretooth track down Mystique in Paris. After chasing her, Mystique shapeshifts into his mother. This weirds out Sabretooth. Mystique runs to the Eiffel Tower to her date, Wolverine.
