I'm not entierly sure how I feel about Keppler. I suppose mostly it's another instance of TPTB dropping the ball and seeing the arc through. There was so much promise and yet, we didn't get enough time to know Keppler or care that he was bad?/good?/dead. Which also made Cathrine's (over) emoting ring false. She knew this guy for what, three days?

I know they thing that people only tune into see WP, but If your going to have a character leave for a bit -- have them leave. Don't put in the two second glimpses and have them in the first and last episode of the arc. Make us miss them!

On Sofia leaving or not - I'm likeing her right now, but she really doesn't make or break the show for me. I'll reserve judgement until I see how they get rid of her. (or not)
