Forgive me for posting before finishing the episode, but at the beginning of the finale all I can do is root for Beck to quickly grow some street savvy! I mean, I don't know how I'd react in this situation and her whole world is being shaken, she doesn't have the luxury of having much time to think rationally, so I can't necessarily claim I would be any more clever than her in that situation... but I REALLY wanted her to get what was going on quickly enough to play along with it and get herself out of there. "Oh, Joe, this is actually kind of hot - I know its weird, but having you in control is kind of a turnon" and "wow, I've never known someone who would do that much for me, risking themselves - it makes me realize how much you love me". If she was able to say all that with the right acting, she could probably get out of there and have a chance to go straight to the police. Similarly, at the end of the last episode, since she was smart enough to try to act normal and try to get out of there, she should also have been smart enough to immediately text Annika all the creepy details she had found and that she felt she was in danger.
