EastEnders scandal in early iPlayer release as unexpected characters kiss

This article contains spoilers for tonight’s episode of EastEnders, which airs on BBC One at 7.30pm or can be streamed now on iPlayer.
Two Albert Square locals have shared a shock kiss – and it’s not the first time they’ve got together.
The instalment kicked off with problems at the Beale-Branning residence, with Peter (Thomas Law) continuing to struggle to bond with his young son Jimmy following his visual impairment diagnosis.
Hearing Penny Branning (Kitty Castledine) speak so positively about the youngster’s disability was uncomfortable for him to hear, and he rushed out onto a run to clear his head.
Lauren (Jacqueline Jossa) noticed his discomfort, especially when their neighbours rallied around to support them both.
She wasn’t the only one who had clocked how much Peter was struggling – his mum Cindy (Michelle Collins) and grandmother Kathy Cotton (Gillian Taylforth) put their issues to one side to stage an intervention.
During their conversation, Lauren became emotional, explaining that Peter clearly doesn’t want to look at either her or Jimmy, and that he isn’t supporting her.
After lashing out, stating that he’s the breadwinner, Peter confessed that he blamed Lauren for Jimmy’s impairment as a result of her drug addiction during pregnancy.
Kathy felt that he took a step too far, and told him to leave. However, before he had chance, Lauren slung the baby monitor at him and entered self destruct mode.
She stormed into The Vic and demanded a vodka from Linda Carter (Kellie Bright), who refused to let her relapse. Before Lauren had opportunity to grab a drink at Harry’s Barn, Linda pre-warned Gina Knight (Francesca Henry).
Meanwhile, back at home, Cindy told Peter that he went too far and offered her own parenting advice. Alone, he began to sing to the child, unaware what was happening a few doors away.
After finding Lauren in a state of despair, Zack Hudson (James Farrar) brought her to his flat, and the pair kissed.
Viewers will remember that they slept together last year, which ruined his marriage to Whitney Dean (Shona McGarty).
Will their kiss ruin her chances at a future with Peter?
