Robert spent 6 years behind bars after killing rapist Lee Posner. Since his release, he and Aaron have found their way back to each other – though Robert "forgot" to mention that he was married to Kev.

Tonight, Robert revealed that there was something else he'd "forgotten" to mention to Aaron – he hadn't been locked up on the Isle of Wight, he'd actually been transferred back to Hotten.

Robert vowed to tell Aaron everything, setting us up for tomorrow's special standalone episode.

Robert received devastating news in Emmerdale

During tonight's episode (November 11) Robert and Kev returned from their mini-moon in London, after renewing their vows last week. Kev was eager to keep moving the relationship forward and wanted to move in with Robert and Victoria.

As Robert and Victoria debated Kev's request and figured out how to say no, he arrived at the cottage. But he didn't want to talk sleeping arrangements, he was there to deliver bad news instead.

"I've got something to tell you," he told Robert. "It's Jez. He's killed someone in prison."

Robert was in shock as he shared with Victoria his own experience with Jez in prison. "It could have been me that he killed," he said.

Robert explained: "He hated me from day one. I was the new boy. He thought I was an easy target. From then on, he was in my face all the time. I was too posh, too pretty. He spread lies about me, why I was inside."

Robert then went on to share that Jez's mates used to beat him up and the abuse only stopped when Kev stepped in.

Robert made a confession to Aaron

After Kev left, Aaron popped round – with Victoria telling him that Robert had received some bad news.

"I wanted to see you. I needed you," Robert told Aaron. He then shared the bad news, saying: "This guy's been murdered in prison. By someone who wanted to do the same to me."

Robert explained that he thought after he walked out of the prison gates he'd be able to just leave all that stuff behind him.

Aaron comforted Robert, telling him this guy will not be getting out of prison anytime soon and reminded Robert that he's "miles away" on the Isle of Wight.

Robert then revealed that wasn't the case and that he'd held back some key information from Aaron. "I wasn't on the Isle of Wight. I got moved back," he admitted, before confessing he had been locked up just up the road in Hotten.

Robert went on to explain that there was so much he hadn't shared with Aaron about his time in prison, including why he and Kev were so close. "It's time I told you everything," he added.

Special episode to explore Robert's time in prison

The ending of Tuesday's episode sets us up for Robert's special standalone episode tomorrow (November 12), which will explore his time in prison via a string of flashback scenes.

Last month, Emmerdale revealed it would be airing 3 special episodes. Two of those, involving April Windsor and Bear Wolf, have already aired – and now it's time for the final one.

Previously speaking about this episode, Ryan Hawley, who plays Robert, said: "The flashback begins around five years ago. We go through different time periods right up until May of this year, just before Robert is let out and interrupts Aaron and John's wedding."

Robert will detail to Aaron all about his trauma at the hands of prison bullies as well as how Kev saved his life. Ryan also teased a twist, explaining: "There's one particularly nice little twist. Something happened in prison that is massively pivotal. No one finds out about it until it's revealed here."
