While EastEnders’ Callum Highway (Tony Clay) has had numerous warnings about his affair with Johnny Carter (Charlie Suff), he can’t seem to get him out of his head.

Johnny has been away on a cruise with his mum Linda Carter (Kellie Bright) over the last few weeks, but for Callum, absence has made the heart grow fonder – despite still being married to incarcerated Ben Mitchell (Max Bowden).

But when Johnny finally returns to Walford in the BBC soap next week, Callum gets an unexpected shock from his lover.

Forthcoming scenes find Callum elated to see Johnny again, but sadness follows when he later spies Johnny on a date at The Albert.

Callum can’t help but feel jealous, but the pair are thrown back into each other’s orbits later in the week when Johnny helps Callum navigate a delicate situation with his stepdaughter Lexi Pearce (Isabella Brown).

Given the clear attraction between them, we can’t imagine it will be too long before they fall back into each other’s arms…

However, they could risk the wrath of Callum’s father-in-law Phil Mitchell (Steve McFadden), who violently attacked Johnny last month after finding out that they were hooking up.

The plot is building towards Ben making a return to EastEnders later this year, where he is likely to learn all about Callum’s infidelity.

The popular character is currently serving a six-year prison sentence for fraud in the States, but it was recently confirmed actor Max Bowden will be reprising his role for a short stint.

Ben will be released on temporary license to support Callum at the funeral of his estranged father Jonno.. !

Jono’s funeral episodes will also see Callum’s brother Stuart Highway (Ricky Champ) make a brief return.

Teasing the drama the pair’s return could bring, a spokesperson for the soap said: ‘With Callum having recently cheated with Johnny, and with those feelings expected to grow, Ben may not be revisiting the happy family he left behind.

‘Whilst both characters are only back for a short stint as Ben is on day release from Prison, and Stuart has a life away from the Square with wife Raine, you’d think that all things would be smooth sailing, but this is Walford, and a lot can happen in a short amount of time…’
