I've just watched the show. I don't know what to think, I'm going to miss Simon, he was my favourite character. Also I wasn't expecing Kelly not to be anymore, so that was a shock. I agree with you about the way they put Kelly out. Even the previous seasons were violent and bloody I think this was too much, some humour is missing, Rudy isn't enough. Curtis never was the strongest character and I think know the writers will put him in that role with Rudy because they are the most important ones. The fact that Curtis is in comunity service since the first season is a bit strange, I thought maybe he was going to finish it and have a most interesting role out of that place.
I wasn't convinced about the episode, it's a bit repetitive. I hope they won't kill the probation officer, that will be too much (but of couse it's going to happen). I will watch this season because, well I watched the previous ones and want to know how the story will end.
