During his time in Emmerdale, Parr has been involved in a number of high-profile storylines, including an affair with policewoman Donna Windsor (Verity Rushworth); taking part in a violent robbery at Home Farm; an illicit affair with his brother's fiancée (later wife), Debbie Dingle (Charley Webb); and secretly fathering a child with Debbie's mother Charity Macey (Emma Atkins). In 2018, Ross Barton was the victim of an acid attack, leaving the character badly scarred. Parr has described the storyline as challenging.
In early 2018 it was announced that would be leaving Emmerdale later in the year. He has suggested he would like to work in the U.S.
