At the end Phil told Shirl to go and say sorry to her son thinking of Deano, but after storming out of the Vic over the bath incident, she returned to the pub and told Mick she's sorry!
Wow! Well spotted everyone. I watched it but didn't pick up on the fact that she was his mum. I just thought she was saying sorry for trying to drown him. Hmmm. That makes things a lot more interesting . . . .
