EastEnders’ Felix Baker moves in with Johnny Carter next week – then jumps to the conclusion that his partner is cheating on him.

The cute couple’s love bubble bursts when Johnny is spotted cosying up to Callum. But has Felix got the wrong end of the stick or has his boyfriend already found another man?

“What started out as a casual thing has got pretty serious,” explains our Albert Square insider. “Are the boys heading for a happy ever after, or is this moving too quickly?”

That thought certainly crosses Linda’s mind when she discovers her son is planning to shack up with his new boyfriend.

Having shied away from a committed relationship, the fact Johnny – who has previously preferred to be single – now wants to live with Felix and make things official raises some eyebrows.

It’s not just Linda who’s surprised at this development – Johnny’s mate Callum also didn’t see this coming and can barely conceal his concern.

Felix is so preoccupied with his love life he’s stunned when Bernie reveals the mess she’s in with the Panesars, unaware of the trouble his relative has got herself into.

Bernie explains the situation, admitting that she has been stealing from the family’s business accounts, and Felix tries to convince her to tread carefully.

But after dishing out some much-needed advice, it isn’t long before Felix is dragged back into matters of the heart when he sees something that makes him suspicious…

“Felix sees Johnny hanging out with Callum, and the pair look pretty close,” says our source. “He doesn’t like what he sees and immediately feels a pang of jealousy.

“Johnny later says he can no longer attend Walford Pride because he’s visiting Elaine in hospital, following her scary collapse in The Vic. But this sets off alarm bells for Felix, and he wonders if that’s the real reason he’s cancelled…”

Is Felix right to be worried about Johnny potentially playing away, and is their relationship in trouble?
