Jason Grimshaw, is a fictional character in the UK television ITV soap opera, Coronation Street. Portrayed by actor Ryan Thomas, the character first appeared during the episode airing on 25 December 2000, when he comes looking for mother Eileen (Sue Cleaver) at the Battersbys' home.
Jason is very much the opposite of half-brother Todd. He is very self-centred and lacks forethought. He is also quite bigoted, being strongly homophobic, though he has mellowed out, and seeing infidelity on the part of men as just a bit of fun. Jason is the son of Eileen Grimshaw and a man called Tony, but for many years didn't know his dad.
Upon his arrival on the Street with his family he was as aspiring runner something which Eileen didn't completely approve of. He worked for a brief period in Sally Webster's hardware shop in 2001 until the failing business went up on fire. He was the one to discover a traumatised Toyah Battersby lying in the ginnel following her rape in April 2001 when he was out jogging early one morning. Although Jason has had many girlfriends, all of them have been quite short-lived since he is commitment-phobic and insatiable with his sexual desires. He has had romantic/sexual relationships with such Street residents as Candice Stowe and Sarah Louise Platt. On Christmas Day 2006, a baby was left on the doorstep of the Grimshaw's, the baby was apparently the product of a one-night stand between Jason and her mother, Emma.
Despite his homophobia, Jason stuck by Todd when others, such as Gail Platt, persecuted him because of him being gay. Despite later on being involved with Sarah Louise, Jason always despised Gail and even though his mother Eileen is now friends with Gail, Jason still hates her.
