Young dad Chesney's girlfriend Katy Armstrong this Thursday (August 16) offers to be a surrogate to disabled sister Izzy, who lost her baby with Gary Windass last month.
Speaking to ITV.com, the actor teased of the potentially long-running plot: "I think he may struggle with the birth as it would bring back memories of baby Joseph.
"This may lead to problems with giving the baby to Izzy and Gary, as Katy and Chesney may grow attached."
The Weatherfield favourite revealed that his alter ego initially "starts warming to the idea".
Georgia May Foote, who plays Katy, recently told Digital Spy that she doesn't believe her character hasn't "thought it through as much as she could have done".
Details of the storyline first emerged early last month.
