Jack Branning might want to watch his back over the next few weeks on EastEnders.
Despite baby mum Sharon Mitchell insisting that Lisa Fowler's comments at the wake are just "delusions", it seems like Phil isn't quite convinced.
As the pair attended the wake in the Queen Vic, hardman Phil's suspicions were aroused when he saw his wife comforting Jack.
The pair innocently spoke about their grief over Mel's death, but Phil clocked on to them holding hands.
And Phil's suspicions were heightened even more when a hysterical Lisa announced that Sharon's baby wasn't Phil's.
What will he do? And could he kill Jack?
Later in the week, Phil is determined to get some answers and a panicked Keanu tries to convince him that Lisa isn't well.
When Phil turns up in Lisa's place, he discovers that she has been taking her medication and despite Keanu trying his best to convince him otherwise, Phil is hellbent on unearthing the truth.
At the end of the week, Phil finally confronts Sharon about Lisa's accusations but she rubbishes the claims.
Phil ends up feeling guilty - but, with the thought in his head, will he end up targeting the wrong person?
