The actor's alter ego Syed Masood has found himself tempted by Danny in recent weeks, but Monday's (October 15) episode saw Syed punch his new love interest after being pushed too far by his mischievous advances.
Speaking on This Morning today (October 18), Elliott promised that there is more drama to come involving Gary Lucy's character.

Elliott commented: "He returns - he can't be punched in the face in the Argee Bhajee and leave without his dignity! He's got to come back and get some sort of revenge, and he does."
He continued: "Gary Lucy comes back and Christian becomes involved in a storyline with him, which involves the police and possibly arrests."
The 32-year-old also said that he is pleased the Masood family now accept Syed's sexuality, after recent episodes saw them fully supportive of his civil partnership with Christian.
Elliott explained: "I think that's been really important. Obviously there's been a three and a half year build to them getting married, and I think there has been a huge shift. But then I think when we started the story, we were surprised by how accepting the audience was and how ready they were to see something like that. It's been brilliant."
The soap star has already filmed his final scenes at EastEnders and is now appearing as a "down and out" character in a production of Tape at the Trafalgar Studios in Whitehall, London.
Asked about his future plans, he replied: "The play runs until November 10, and then after that I'm hoping that I'll get a bit of a break. But if work comes up, I've got to take it at this stage."
EastEnders continues tonight (October 18) at 7.30pm on BBC One.
