Ok so i'm doing whitewash and i go into the cell to bully the guy. chick comes in tells me to stop few seconds later she tells me to bully him some more so i go in continue to beat him like a red headed step child and now i'm stuck in the cell wtf what do i do?!?!
you have to keep beating him until she tells you to stop and/or he finally initiates conversation with you. Then and only then, will the door unlock allowing you to leave.
That's why I always make a new save. I recently deleted 405 of them (was getting slow opening the load screen). That and the quick save is always deleted when I close the game.
