So, I'm really really hoping that it was Kim that went back for Rose. That she's not killed her but she's hiding her somewhere because she knows what an absolute snake Will is and she's planning some sort of dastardly revenge on Will.
I mean, who the f*ck does he thinks he is talking to his wife like that? It's spoon face saga all over again.
Kim is not back sleeping in the same bed as Will so there is something amiss there, she doesn't trust him.
Hoping that Kim has got some master plan is the only thing that can salvage this shit show.
