George faces the darkest times of his life next week as he is held captive by evil human traffickers Deena (Sian Breckin) and Graham (Steven Marsh) once again.
Roberts told Inside Soap: "It's been hinted at in previous episodes that Deena and Graham want to force George and Phoebe into prostitution. Their intentions become clearer [next] week, when Deena announces that a man called Mr Evans is coming to visit George - and it's obvious that they won't just be playing card games together.
"George is terrified at the prospect. He's imprisoned with no way to escape."
Despite helping Deena by betraying George, Phoebe (Mandip Gill) also remains a captive.
Roberts added: "Phoebe's the stronger one of the two of them, so Deena drugs her. She begins to slip in and out of consciousness as a result, and George's only lifeline is slipping away before his eyes.
"The episodes are quite shocking and dramatic. George's friends in the village realise that he's gone missing - so it's a matter of if, how and when he might resurface that the audience will have to watch out for."
Hollyoaks airs weeknights at 6.30pm on Channel 4 with a first look screening at 7pm on E4.
