Adam will take a pop at every pretty bird in the street and try to copy his late father. He will forget all about the life he built up in Canada and squeeze into Ken's overcrowded home, and probably work at the factory to be engrossed in edge of your seat storylines such as factory orders and dodgy clients.
Maria will whine whine whine, Caz will be caught, allowing Maria to be released and move on with her life, leaving the Weatherfield plod to accuse another innocent soul of murder based on little evidence.
Phelan will smirk, scheme, lie to the dozy Eileen, smirk more and sneer. After further recycling and milking of this plot he will either be killed off or packed off to prison, with Eileen asking herself how she could be so stupid to fall for his lies.
I think that about sums it up.
