Coronation Street’s Anthony Cotton, who plays hot-pot King Sean Tully in the award-winning ITV soap, has defended his character’s suspicions in an upcoming storyline in which he believes that his partner, Marcus Dent (Charlie Condou) is cheating on him.

We were all so happy when Marcus came back to the cobbles of Weatherfield and mended Sean’s broken heart, but it wasn’t long before we noticed the cracks that broke their relationship in the first place coming back to haunt them.

With the reuniting of Sean’s son to his natural father came a longing from Marcus to have a child of his own, a notion definitely not shared by Sean.  After weeks of will-they-wont-they, Sean finally plucked up the courage to admit his true feelings to his partner, but we all knew it wouldn’t be long before the seeds of resentment were formed, despite Marcus accepting his decision.

Since then, Marcus has become overly involved with good friend, Maria (Samia Ghadie) and her little boy, Liam, and for  a while there, as Maria developed a crush on the gay midwife, it looked like perhaps the idea of an affair between the two of them wasn’t as far-fetched as we might have thought.

However, according to Digital Spy, it’s the introduction of a new work colleague of Marcus’, Aiden, that is set to get Sean’s imagination racing with regards to the loyalty of his partner.

Sean is set to get very jealous indeed over the newcomers friendship with Marcus, but Anthony Cotton, the actor who plays the Underworld factory worker, says he can understand his characters insecurities.

Speaking on popular daytime chat show, ITV’s  This Morning, Cotton said: “Sean, all of a sudden, is jealous.

“Well actually, there’s a reason why, because Marcus has spent loads of time with Maria and now this Aiden’s tipped up, so it’s getting on his nerves, I think. That’s quite understandable.”

However, Cotton went on to hint that his suspicions may not just be the result of paranoia, adding that he believed that the new work friends friendship may well develop into something more given time.

“It’s not the case at that moment. But we must all learn to honour our instincts, because I think that Sean’s instincts might prove to be right. And I can’t say any more than that!”

Speaking about the child situation that has been bubbling under the surface of Sean and Marcus’ relationship, the actor explained: ”They do want different things.

“Sean already has his son Dylan and it’s a big responsibility, so he doesn’t want to do something just for the sake of keeping something going that maybe has run its course.”
