The fiesty mum abruptly left Walford in recent episodes after getting a suspicious phone call on the day that Whitney Dean (Shona McGarty) was released on bail, after she murdered Leo King (Tom Wells) in self-defence.
Fans will remember that Kush also had a part to play in her homecoming, changing his plea to guilty of assault after he pushed Leo from the balcony of The Prince Albert pub, after he stumbled upon the villain attacking Whit.
Kat left him holding the fort, trusting him to take care of her family while she’s away.
While pleased Tommy has opened up to him in such a way, Kush needs to decide what’s best for the youngster – to tell his mum or to keep it all hush until he’s ready to tell her himself.
But will he be able to keep his secret now he’s responsible for her family?
Will he spill Tommy’s woes to Jean Slater (Gillian Wright) or Mo Harris (Laila Morse) instead?
