Admittedly, I don't like Tamsin. But she was on to something here. I don't think Bo lost her succubus, I think she knew she goofed choosing Rainer over all of them and needed all of them to say they loved her or would be there for her. I applaud Tamsin for not falling for Bo's self-imposed pity party in this scene. Kenzi wasn't around to coddle Bo as usual.
