Well I just read the spoilers and Cain crashes his car into a wall and ends up in a bad way. I think this will tie in with Debbies return which will probably tie in with Ross' exit.

My theory is that Debbie will come back to support Cain and expose Ross to his family as Roberts shooter. Emma, James and Finn will then disown him and ban him from seeing Moses. Then he will probably go missing for a while like he has a few times. Then hopefully he will return with a massive storyline.
