Right when the sun purged through the window, Vivienne was up and about; scanning her surroundings to come up with a plan to escape, and be on her way. The hole in the wall was one option -- but she was way too big to even fit (being the size of a cannonball would suffice). Then, she looked upon the cell door, realizing that these things had a lock on each of them in this bloody hell of a brig. Reaching around in her hair, she found one of those spare hair clips that she used as a backup to pick locks during times of raiding. Hey, she had to have a "spare key" for every locked item. 

Attempting to pick the lock of her cell, the pirate just heard the door from the entrance, at the top of the stairs. Reacting fast, she was on the floor, upon her back; like how she was last night, acting unconcerned and bored.
