Biography . 1984 - 2009 : Meeting Tyrone Dobbs . Molly was the daughter of Diggory Compton , a baker who opened his shop on Victoria Street . When she first arrived , it emerged that she was a victim of bullying at school , with one of the bullies being Fiz Brown . Molly used to work for Fiz ' s boyfriend Kirk Sutherland , whom she flirted with to get revenge on Fiz . After briefly working in her father ' s shop and at Sutherland ' s Kennels , Molly then started working for Dev Alahan in the Corner Shop . Molly began dating Tyrone Dobbs and moved in with him and his surrogate parents Jack and Vera Duckworth . Molly formed a close bond and friendship with Vera and was devastated when she died in January 2008 . After Vera ' s death , Molly and Tyrone bought the Duckworths ' house and lived there with Jack and also initially Jack and Vera ' s grandson Paul Clayton until he left in May . In July , Molly and Tyrone became engaged . The following month , Tyrone introduced Molly to his mother Jackie Dobbs . They discovered that Jackie was £1 , 000 in debt to Brian , an old friend of Tyrone ' s father and much to Molly ' s despair Tyrone agreed to help her . They used their wedding savings to pay him off and put their plans on hold for Molly to afford her dream wedding dress . In December , Molly became suspicious of Tyrone ' s behaviour . He had secretly been selling dodgy merchandise with her aunt , Pam Hobsworth , to help pay for their wedding , but Molly mistakenly thought that Tyrone was having an affair . When Tyrone confessed that he had been selling with Pam , Molly was furious and left him , saying that she can no longer trust him . She later forgave him , and they married on 12th January 2009 . 2009 - 2010 : Affair with Kevin Webster . Molly struck up a friendship with her husband ' s married workmate Kevin Webster . The pair , along with Jason Grimshaw , trained together for the local fun run . Although Kevin jealously accused Jason of sleeping with Molly , she laughed it off and they remained friends . Kevin was the only person to support Molly at the event and soon found himself falling for her and told her of his feelings . Although Molly was shocked , she couldn ' t help but feel excited and , having grown bored of her marriage to Tyrone , they later began an affair . A guilty Molly then ended her affair with Kevin and went on holiday with Tyrone but after another fun run she and Kevin had sex in a hotel . The affair continued and although it was initially intended to be a fling they found themselves falling in love with each other and on Christmas Day pledged to leave their respective spouses and start a new life together . However , Kevin ' s wife Sally Webster had a confession of her own before he could say anything - she had breast cancer . Kevin decided he couldn ' t leave Sally when she was ill and quickly went over to Molly before she could leave Tyrone and hold her the news . Molly remarked how unfair it was , but not for Sally but for them . Kevin was appalled at her selfishness and ended the affair , telling Molly that his commitment was now to Sally . In January 2010 , Molly promised to be a better wife to Tyrone upon their first wedding anniversary . However because of the affair she had fallen out of love with him and when the anniversary of Vera ' s death arrived Molly decided she couldn ' t live with him any more and left . She denied that she has been seeing someone else and moved into the flat above the shop . In March , Molly was shocked to discover that she was three months pregnant , with the father either being Kevin or Tyrone . When she informed Kevin of her pregnancy , he refused to have anything to do with her and coldly burned the baby scan picture in front of her . With nowhere left to turn , she told Tyrone about the pregnancy and they reconciled . Molly and Tyrone found out that she was expecting a baby boy . Kevin demanded Molly had an abortion and pass it off as a miscarriage , which she refused to do . On 19th April 2010 , Tyrone asked Kevin to check up on his car . Whilst fixing it , Kevin was distracted by his daughter Sophie . Thinking that the job was finished , Tyrone took the car and drove it through the countryside with Molly to tell Diggory the news about her pregnancy . The brakes failed and the car somersaulted into a field . Molly was injured , putting the unborn baby in danger too . Tyrone stayed the night at Molly ' s bedside and received the good news that she was stable . When she regained consciousness , Molly asked Pam what happened and she revealed that Kevin didn ' t fix the brakes . Molly accused Kevin of trying to murder her and the baby . Eventually she decided against telling the police . Molly then tried to persuade Tyrone to move away as it ' s not fair on him or the baby to be around Kevin . Molly gave birth to her son Jack on 6th September . The speed of her labour meant that Sally and Kevin had to deliver the baby . After Kevin agreed to him and Sally being godparents , Molly was furious as she wanted Kevin to play no part in Jack ' s life . At the christening , Kevin stole Jack ' s dummy in the Rovers for DNA testing . Kevin received the DNA test results in November , proving that he was the father . He showed the results to Molly and she was distraught and furious with Kevin for going behind her back . A terminally - ill Jack Duckworth overheard the conversation and told Molly to either move away with Tyrone and get away from Kevin , or end the marriage if she didn ' t really love Tyrone . This proved to be their last conversation as he died hours later . 2010 : Death . On 19th November , Molly told Kevin that she was still in love with him . However , Kevin told her that he loved and wanted to be with his wife , Sally . Realising that Kevin no longer had feelings for her , Molly was left heartbroken . For weeks , Tyrone had been pushing Molly to have another baby with him . When he discovered that she was still on the pill , he confronted her . After much soul searching , she decided to leave him for good in early December . Tyrone told her that she could not take his son with her , prompting her to confess that Jack was not really his son . She left with Jack , refusing to tell Tyrone who the baby ' s father was . As she headed to catch a bus to Diggory ' s house , she stopped at the Corner Shop to say her goodbyes to Sunita Alahan . Kevin turned up at the shop and while Sunita was in the back of the shop , Molly told Kevin to say goodbye to his son . After saying goodbye , Kevin left the shop and crossed the road before a massive gas explosion ripped apart the Joinery Bar in the viaduct at the end of the street . Molly was dazed by the blast and walked out of the shop cradling Jack . As she opened the door , she was horrified to see the blast had derailed a tram which was falling towards the shop . She ran back inside as the tram hit and destroyed the shop , burying her and Jack in rubble . Emergency services eventually reached Molly and Jack . Jack was taken to hospital but specialist equipment was needed to be able to move Molly . The wait was proving critical as Molly was bleeding heavily , and Sally was allowed to enter the building and comfort her . Molly told Sally that she was dying and that Jack was going to need his father . When Sally told her that nobody knew who Jack ' s father was , Molly told her it was Kevin . Molly begged Sally not to hate her , but all a horrified Sally could do was watch as Molly died moments later . Legacy . Molly ' s confession to Sally had caused her and Kevin to separate . On the day of Molly ' s funeral , Tyrone had twigged that Kevin had the affair with Molly and was Jack ' s real father , and punched him causing Kevin to fall into the grave and on top of Molly ' s coffin . In the aftermath of the events , Kevin was a single man once again and Tyrone had given him Jack to take care off , as he couldn ' t cope with raising his son . Sally also had a less sympathetic outlook on Molly and hated her for causing a wedge between her and Kevin ' s relationship . Tyrone ' s confidence in particular was destroyed due to Molly ' s betrayal , although less than a year after her death he had met Kirsty Soames , although that relationship would turn out for the worse . On the first anniversary of the tram crash , a tribute was held for Molly along with other fallen victim Ashley Peacock . The relationship between Kevin and Tyrone had became quite frosty due to the affair , although the pair would eventually make up by 2013 . Even though Sally and Kevin tried to make a go of their relationship several times , Sally made it clear in 2012 that she couldn ' t face raising Jack as it would remind her of the affair . Since then there has been no reconciliation between the pair . Quotes . " Hey , hey , hey ! What ' s all this racket ? " ( First line , to Maria Sutherland ) .
