Oscar Branning (Pierre Moullier) is set to do something ‘awful’ to Peter Beale (Thomas Law) in EastEnders next week.

The newcomer has made quite the impact on Albert Square and viewers alike ever since he arrived in the BBC One soap last week.

Sister Lauren (Jacqueline Jossa) was forced to take him in after being released from a three-month stretch in a young offenders institute, where he’d spent time for joyriding.

Their mum Tanya (Jo Joyner) had made it clear that he wasn’t welcome to return to her house as a result of the dodgy characters he was hanging around with.

When Oscar tipped off the police about their involvement in the car robbery, they attempted to petrol bomb his property, mistakenly targeting the neighbours instead.

Despite his attempts to escape his brutish mates, they’ve tracked him down to Walford and are seeking revenge.

‘Oscar feels threatened as Mike (Tai Hilferink) is a serious guy who doesn’t seem to care about getting caught or the consequences,’ actor Pierre told us.

‘Since he arrived in the Square, Oscar has been all fun and games, but you’ll see another side of him this week because Mike wants to make him suffer for what he’s done!’

And Pierre’s right – next week’s episodes see him launch an attack on an apparent intruder, believing it’s Mike.

Lauren learns that the thug has been threatening Oscar, and has left a knife as a way of threatening him. She reckons that their their uncle Jack (Scott Maslen) should be alerted for protection.

‘Oscar believes getting Jack involved will only make things worse because if Mike finds out that there’s a policeman in his family, he’ll be even more on [his] case,’ Pierre explains.

‘I think that because Oscar is a smooth talker and he’s been getting himself out of tight spots all his life, he believes he can do it again…’

Things soon kick off, and Jack’s forced to intervene. Lauren gives her brother a final warning, but that night, his paranoia intensifies when he hears a noise coming from the hallway.

Sneaking up on a hooded figure, he goes in to attack – unaware that it’s actually Peter Beale (Thomas Law) in his dressing gown.

‘It’s so awful for Oscar when he realises that he’s done this to Peter, who has been kind enough to take him in.

‘Oscar plays lots of games with people, but deep down, he’ll do anything for the people he cares for, and Peter has become one of those people, so this is awful.’

And, despite Oscar receiving his marching orders, Pierre reckons there could be one saving grace.

‘No matter how many times he messes up, Lauren is still there for him and backing him, which really surprises him.
