I was able to duplicate this by sitting down and then trying to take something from the book shelf and being seen by Charlene. I was then stuck just as you said. I'm assuming there was some dialogue between Scarlett and Charlene as the camera focused on Charlene. For a while I was stuck with my view on Charlene. I was able to fix camera issue by talking to Victoria. I killed Charlene in hopes that would free me, nope. I used the homestead button but upon asking to make a choice with Scarlett by ZixZaxx the game crashed. I was able to enter Black Cove and she was rejoined with the party.
