Lightning Quick Larcenist is a fake ending in Infiltrating the Airship
The player can get this ending by using the Sticky Hand to enter the Airship and then select Ball and Chain to get the safe the player finds in the ship to the waiting military. Once Henry and the safe are both inside the helicopter the player is informed he achieved this ending, Henry Stickman wins and hugs him and has awarded a single pair of pants for Captain G.
Message for Henry
A winner is you! Congratulations for completing Lightning Quick Larcenist.
