Kat Slater pushes Phil Mitchell aside when she learns a devastating truth about Alfie Moon in Monday's episode of EastEnders (7:30 pm. see our TV Guide for full listings).

Kat Slater has a shock conversation with her ex Alfie Moon, when he admits that their son Tommy Moon punched him the stomach.

Tommy was kicking off after finding out that he was being made a fool of on  social media in a video showing him being publicly told off by his dad.

Following the incident, Alfie and Tommy's stepdad Phil Mitchell decided to take matters into their own hands. He'd already lashed out at Kat in another incident and the situation was threatening to get out of control.

Encouraging Tommy to see that he couldn't go around hitting his loved ones, they took him down the Boxing Den to train properly in the ring.

The whole deal is news to Kat, however, who is stunned by her son's continuing violent outbursts! She's also angry with fiance Phil for keeping it secret from her.

What Kat doesn't realise is that Phil's been keeping it all under wraps partly for Alfie's sake, as the punch led to Alfie going to hospital and discovering he may have prostate cancer.

In trying to placate Kat, Phil lets slip about Alfie's cancer worries and reveals that his results are due out today. Terrified for her former husband, Kat drops everything to be with him at the hospital.

After supporting Alfie, a frazzled Kat returns home and she confronts Phil yet again. Furious with him for keeping such big secrets from her, the couple have a massive row.

Are their wedding plans about to be derailed?

Horrified and feeling humiliated by Jack's fury that she left Lily and the baby alone, Stacey rips off her apron and heads out to find Lily.
