Christian arrives in Walford after inviting Jane to his civil partnership ceremony. She's not keen on going, but Ian finds out and invites Christian and his partner for dinner.
John Partridge said of landing the role: "I'm delighted to be joining EastEnders and playing Christian. I think he's going to upset the apple cart at the Beales'."
