Karen Hollins is scared to be left alone with foster teenager Tom after he attacked her on Doctors. But could Tom also be to blame for his mum's death?

Karen Hollins (played by Jan Pearson) is still in terrible pain, after being physically attacked by foster teenager, Tom Robson (Max True) on Doctors (1:45pm on BBC One, see our TV Guide for full listings).

When Karen's policeman husband, Rob (Chris Walker) catches her taking the painkillers she stole from Jimmi Clay's (Adrian Lewis Morgan) office at the surgery, she has no choice but to admit what happened with Tom.

Rob is furious and gets straight onto social services to report Tom's violent behaviour.

But when Rob confronts Tom and demands to know why he attacked Karen, Tom turns on the tears and Rob starts to feel sorry for the lad.

However, Karen won't be fooled by Tom again.

The worried mum starts to wonder if Tom's violent behaviour also led to his mum's death...

Meanwhile, Al Haskey (Ian Midlane) thinks he's had a lucky escape after FINALLY breaking-up with fiancee, Lily Walker (Verity Rushworth).

But Al's in for a surprise, when Lily turns up at the surgery and tries to convince the medic to give their relationship another chance!

Surgery receptionist, Valerie Pitman (Sarah Moyles) couldn't be happier to see Al squirm, since she thinks he has treated Lily very badly.

But when Valerie realises Lily isn't handling the situation well, she decides to try and help.

Is this the last Al will be seeing of heartbroken Lily?

Elsewhere, Zara Carmichael (Elisabeth Dermot Walsh) is checking out the facilities at a local Letherbridge gym.

Zara sees personal trainer, Marsha Morton (Katharine Bennett-Fox) clash with her boss, Kelvin Fleck (Edward Kelly) over changes at the gym.

However, Marsha is not at all happy with the news when she realises WHO the father must be...
