Arnold told CultBox: “The pivotal bits for Rich’s character are in the second episode, but when we get to Episode 7, which is Grace’s episode, there’s a lot that happens there.”

He continued: “I think the character of Rich is really tested on the strength of his relationship with Grace. I don’t want to spoil it, but this great bond that they have does get very tested.”

Episode 2 of the current series, focusing on the character of Rich, aired on Thursday night on E4.

Describing castmate Jessica Sula, who plays Grace in the show, he added: “She’s just a fantastic girl; she’s a really lovely, bubbly girl. She’s a brilliant actress, she’s really cute and does Grace so well.”
