John takes centre stage again in next week's episodes as he is back in Weatherfield in time for his wife Fiz's (Jennie McAlpine) murder trial. As revealed earlier in the year, he soon holds Rosie captive for a second time and starts coaching her to testify on his behalf in court.
Speaking to Digital Spy about John's desperate plan, Hawley laughed: "She must be the most stable, sensitive and intelligent person that he knows!
"No, I think the real reason is that it's a full circle thing for John. Everything started with Rosie for John, and he feels like he needs her to find some redemption."
Discussing Rosie's attitude towards John, he continued: "It's definitely a scary experience for Rosie, but she can't help herself when it comes to having a dig. With Rosie, there'll always be the odd jibe in there - especially when it comes to John Stape!"
Hawley added that he enjoyed the opportunity to film more scenes with Helen Flanagan, who plays Rosie.
"Most of our scenes were filmed over a couple of days, so we had a full two days together and it was really lovely. It'd been ages since we'd done any big stuff together before that," he explained.
"I really enjoy working with Helen. I've worked with her in these big chunks since she was a teenager, and it's been nice to see her develop as an actress."
Coronation Street airs Fiz's trial episodes all next week on ITV1.
