In my opinion, I don't think that they should've killed Michael off. What him and Jane had was so special and romantic. Although, she did leave him and got with Rafael, he still cared about her and was always doing things to help her. I haven't seen season 4 yet, but if she doesn't fecha the guy that appeared at the end of the last episode of season 3, then she'll probably get back together with Rafael, and they are cute together (don't get me wrong), he also has children with Petra and that will cause tension once again, because when she first had the kids, Jane thought her and Mateo would be left out in the dust.
