Speaking exclusively to
Digital Spy, Kieron explained: "To be fair, Carl has been in a few times now playing different characters but this is the only character so far that has been picked up – that he's going to be playing John Paul.
"I can't really give anything away, but it was nice to work with James again. We've literally not worked together since he left the last time, which was probably about three or four years ago.
"It was nice to have a catch-up, even just discussing what we've both been up to – and getting back to how Ste and John Paul talk to each other and their experiences that they've had.
