In 2010, Jason began a relationship with Rosie Webster (Helen Flanagan). Teasing the storyline, Thomas said "It's going to be a very feisty, sexy relationship between the two characters." Asked if the Jason and Rosie pairing could work, Thomas admitted that with Jason's track record anything could happen. In October 2010, Flanagan commented on the storyline: ""Trust the writers to give it to me! I didn't have time to worry about it - or hit the gym! Ryan and I are like brother and sister so the first kiss was weird, but once we got that out of the way it was fine. "It wasn't as passionate as it looked as Ryan was in agony from an infected tooth. But I'm glad Rosie has got a boyfriend - it shows she has a heart.". In December that year Jason rescues Simon Barlow from No.13 after it caught fire after the Joinery exploded.
