Jimmy is currently facing a tough time on screen as he is suffering from amnesia, which has left him facing the tough task of rebuilding his life with wife Nicola and daughter Angelica.
However, things will soon become yet more complicated when Kelly throws a massive spanner in the works - informing Jimmy that she has a 2-year-old son named Elliot and he is the father.
In an interview with Soaplife, Miles explained: "Jimmy's completely bowled over by Kelly's revelation that he has a son. It's very exciting for him but at the same time a huge shock.
"It's hard for him to take in but, in a way, his son seems as valid to Jimmy as his daughter Angelica, who he doesn't know either."
Following the bombshell, Jimmy is expected to face increasing pressure to choose between Nicola and Kelly as their love triangle storyline intensifies.
Kelly - played by Adele Silva - returned to screens last month and makes a reappearance in the village in tomorrow night's episode, paving the way for her full-time move back to Emmerdale.
