Thanks peeps, I know what you mean, Enders has been jumping out of reality box lately, still it's my escapism of the week, everyone on Yahoo Answers seem to think it will be mad May, I'm inclined to agree, I did think it would be Mickey as he is due to leave.
I say May based on the previous way that baddies/bullies are dealt with.
I think she will be killed of the same way as they kill off any character who is brought in especially to be a bully (ie not a previously "nice" character who has evolved to being a bully) eg Trevor and Stella
It's definitely Mad May. Mickey makes a life changing decision soon and will Keith follow? In August Jim will pay a short visit to the square, it's just been filmed.
