AARON Dingle is traumatised after Billy Fletcher revealed he was moving next door to him – leaving fans terrified he’d relapse on drugs.

The hunk was horrified after seeing prison bully Billy arrive in the Dales last night to be with his mum Jessie Grant.

At the start of tonight’s episode, Aaron launched himself at Billy and warned him to stay away.

But his day turned into a nightmare, as Billy revealed he was moving next door to Aaron and Robert Sugden.

Speaking about his experience of Billy in jail, Aaron explained: I have tried so hard to get past it, with the counselling and telling myself I’d never have to go through it again.

“He was evil. There was a gang of them.

“He stayed in the background but he was still part of it. He had a way of staying under the radar. They would never let up. He was clever. He’d look at you and make you hate yourself.”

Viewers feared Billy’s arrival would set Aaron back and worried he could start taking spice again to cope with the painful memories.

One tweeted: “My poor baby Aaron . He can’t get a break.”

Another added: “I hate seeing Aaron struggling so much.”

When he was quizzed by Marlon Dingle, Billy insisted he was the innocent party and claimed Aaron was the one who bullied him in jail.

Jessie said she’d always side with her son and even Marlon seemed convinced.

But Billy’s brother Ellis wasn’t fooled and warned his Aunt Billy would never be able to stay out of trouble.

As well as upsetting Aaron, Billy has already been accused of breaking into the Dingles’ house – something he’s denied.

When tonight's episode came to a close, there appeared to be a big twist in store, as Billy was seen bloodied and bruised.

But was it Aaron who got his revenge? Or is this a ploy by Billy to get him sympathy?
