Little Simon keeps misbehaving which puts a strain on Peter and the once so strong bond between father and son starts to break down.
Things then get out of hand when Simon goes missing and is later found passed out in Peter's flat after having drunk a whole bottle of wine. Simon is rushed to hospital and thankfully recovers but Peter's is beside himself with guilt so to make things right he tells Simon he can go stay with Leanne.
Simon is as extatic as Leanne is gobsmacked by Peter's gesture but the tables quickly turn on him as Leanne now refuses to let him see Simon again.
With the battle lines drawn, Chris Gascoyne, who plays Peter, said: "Peter wil always fight for Simon and this is going to be a massive fight."
