EastEnders spoiler pictures reveal the fallout of Phil Mitchell discovering the truth, that his pregnant wife Sharon's baby isn't his child.
Phil realised Sharon was repeatedly lying to him this week, with him suspicious of a potential affair with her ex Jack Branning.
But Sharon made Phil feel bad for doubting her, and following the birth of granddaughter Peggy Taylor he decided to turn over a new leaf - preparing for the birth of what he believed was his own child.
That was until Thursday's episode, when he discovered Sharon had lied about her whereabouts when stepdaughter Louise was in labour - with him realising she had gone to see Lisa Fowler at the clinic she was in.
In the aftermath, Phil is now more convinced than ever that he's not the dad and he wants revenge.
Phil told his son Ben Mitchell what he'd uncovered, with him now wanting his help in finding out who the father is.
New pictures reveal the moment father and son begin digging, and it appears there's some damning discoveries.
Looking at a laptop, the pair look a little confused if not shocked by whatever they find out.
Later, Ben makes a separate discovery it seems as he's shown holding a necklace while looking very suspicious,
It's not clear who it belongs to, but judging by the images he appears to find it in Jack's house.
Is this what leads to Phil's determination to make an innocent Jack pay in violent scenes?
Ben is confronted by Jack in a fourth image, no doubt confused to see the Mitchell in his home.
Or perhaps he lets him in, unaware of his true intentions.
Either way, it seems Phil and Ben are instrumental in the truth about Sharon's fling with Keanu Taylor finally coming to light this Christmas.
Viewers can see these scenes in the final episode of the week, on Friday December 13th.
EastEnders airs Mondays and Fridays at 8pm, and Tuesdays and Thursdays at 7:30pm on BBC One.
