Jason Grimshaw Jason Grimshaw , played by Ryan Thomas and was very much the opposite of half - brother Todd when they were growing up , being very self - centred and lacking forethought . Jason is the son of Eileen Grimshaw and Tony Stewart , 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 . Jason is mostly unlucky when it comes to his love life and in recent years has been in numerous relationships such as Tina McIntyre , Rosie Webster , Stella Price and her daughter Eva . He currently remains at 11 Coronation Street with his mother Eileen and their lodger and friend Sean Tully . Relationships . 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 Platt . He seemed to have finally settled down somewhat with Violet Wilson , even going as far as uncharacteristically promising to look after her when he falsely believed her to be pregnant , however , they broke up after he was unable to cope with her confession that she had shared one drunken kiss with Charlie Stubbs . While they were apart he began seeing Sarah , and continued the affair even after he and Violet reunited . Eventually Violet found out and left Jason for good . He continued seeing Sarah , much to the dismay of their mothers . Their relationship remained rocky as Sarah still felt insecure over his relationship with Violet and the fact he proposed to her while still with Sarah . This led to a furious showdown in which Sarah publicly dumped Jason in the Rovers by throwing his pint over his head . After only days of bickering , Jason decided to win Sarah back , and after she refused to speak to him , Jason drastically broke into her house and asked her to marry him . She accepted , although they had a cool reception from both their mothers . They announced their engagement in the Rovers in front of Violet , which Sarah had wanted to do to make a point . The wedding though was a disaster . Jason decided it wasn ' t for him , and escaped through the Registry Office toilet window , leaving Sarah heartbroken . After months of ignoring him because of his actions , she slowly started to come round and began seeing him again . But on Christmas Day 2006 , Jason had a major surprise delivered to the front door in the shape of a baby - his little girl , Holly by a young woman called Emma . Charlie ' s murder , ' Holly ' . In January 2007 , Jason lost close friend and workmate Charlie Stubbs . Jason was very upset by Charlie ' s demise , who had been murdered by Tracy Barlow . Along with Maria Sutherland , Jason saw through Tracy ' s self - defence story and gave evidence against her when she stood trial for his murder . On Christmas Day 2006 , a baby was left on the doorstep of the Grimshaws ' , the baby was apparently the product of a one - night stand between Jason and her mother , Emma . Jason took a long time to get used to being a father , he was helped however , by both his mother and girlfriend . In April 2007 , after seeing reports of the murder trial of Tracy Barlow , Emma , realised that it was Charlie who fathered her daughter rather than Jason . It seems that Charlie gave a false name when he had a one night stand with Emma . When Emma dropped Holly at Jason ' s on Christmas Day , she did not see Jason , only his mum Eileen and therefore genuinely believed that she had left her daughter in the right place . After a custody battle with Emma , Eileen agreed to return Holly to her mother . " Befriending " David Platt . Jason ' s future mother - in - law , Gail Platt bribed Jason onto keeping an eye on her evil son David Platt , but it wan ' t easy for Jason . David dragged Jason onto the roof on 20th August , and confessed that he wanted to murder his whole family , leaving Jason stunned . When David was thrown out of his home , he vowed that Jason would not marry Sarah , and since then Jason has had to watch his back continuously . In his most violent plan to date , nasty David unbolted all the bolts on some scaffolding , and Jason went plummeting to the ground below , ending up in hospital . It was then that he had to confess to Gail what happened on the factory roof . Jason married Sarah on Halloween , 2007 . David invited Jason ' s brother Todd to the wedding in the hope of causing havoc . However , his plan backfired and things didn ' t look too good for the big day . David - in a further attempt to sabotage the wedding - faked a suicide whilst the wedding ceremony was in progress , but Sarah insisted that they carry on regardless . Marriage , Sarah ' s departure . David ' s fake suicide attempt put Jason and Sarah ' s marriage on the rocks . Gail let David stay at No . 8 and the couple ' s honeymoon was cut short as while Sarah knew that it was just a stunt to ruin the wedding , Jason didn ' t believe it . Also on 5th November , after Jason was going to take Sarah ' s wedding dress to the cleaners he accidentally left it in Roy ' s Rolls which got picked up by David . He put it in a puddle before placing it in a bin bag with the other bits and pieces the Morton children got from their neighbours . The Mortons ' Guy Fawkes got first prize and whilst being burnt , Sarah recognised her wedding dress before Jason admitted that he accidentally lost it somewhere . Sarah knew straight away that this was all David ' s doing . Jason , Sarah and Bethany were set to leave for Milan on 30th December , after Sarah bagged herself the job from her uncle Stephen , but Jason backed out leaving Sarah and Bethany to go alone , when Sarah admitted to him that she had planted the drugs in David ' s drawer at the salon . On New Year ' s Eve 2007 , Jason and Becky Granger had a lingering kiss as the midnight chimes rang , and on 1st February they slept together . Jason regretted it the next morning and went to see Sarah in Milan to tell her he had slept with Becky . Instead of forgiving him , she gave him a black eye . When he returned to the Street , Becky hit him as well . Several months later , after some flirting , Jason slept with Becky again and they became a couple . However , they argued when Jason wanted to have a night in on his own . Father ' s death and leaving the street . Jason was devastated to learn that his father Tony Stewart had suffered a fatal a heart attack in April 2016 . He began to lash out at anyone who he felt disrespected his father and contributed to him leaving the area several months back . The heartbreak didn ' t end as Tony was suspected of killing Callum Logan out of retribution for Callum attacking Jason in the ginnel and hospitalising him . Jason ' s " friend " and colleague Pat Phelan hid Tony ' s toolbox which may have contained the murder weapon , but in the end Jason decided to retrieve it from Phelan and hand it into the police . The police concluded that they were certain Tony killed Callum as a wrench with Tony ' s finger prints and Callum ' s blood samples was discovered . Callum ' s friend Gemma Winter warned Jason that Callum ' s mates were looking for revenge . Shortly after this , Jason ' s van was torched outside the Builder ' s Yard , although he was unaware that Callum ' s mates weren ' t responsible , but a manipulative Phelan . Phelan persuaded Jason to take a break and get his head straight . Jason agreed and left Phelan in charge of the yard . After a farewell to his family and friends , Jason left . During his stay in Thailand Jason got drunk and had an accident , which was attributed to his stress knowing his father was a ' murderer ' . Eileen flew over to take care of him . Jason agreed to invest his father ' s money in a property development project which was suggested by Phelan , unaware that Phelan and his mate Vinny Ashford were using the venture as a front for their scam and no flats were actually being developed . Vinny took the money along with cash invested by buyers of the flats , leaving Phelan behind penniless . Phelan broke the news to Eileen that Vinny fled with the money , and she informed Jason over the phone . Despite losing his money , he didn ' t blame Eileen or Phelan for the incident . Quotes .
