Marcus Dent Marcus Dent was a midwife and former sonographer at Weatherfield General , introduced when Violet Wilson went for a scan . He gave his number to Sean Tully who was also present . The two started dating but Sean wasn ' t sure how the relationship should progress . Sean tricked Marcus into revealing the sex of the baby to him as he wanted to know and Violet didn ' t . This caused problems briefly when Violet threatened to report Marcus for unprofessional behaviour but was persuaded not to and the couple continued dating . Marcus delivered Violet ' s son , Dylan , in the Rovers Return Inn on 22nd February 2008 . Violet and her boyfriend Jamie Baldwin later left Weatherfield to escape Sean . Marcus quit his sonographer job to try to find more fulfilling employment . He and Sean planned to get a place together but Sean briefly losing his job at Underworld put their plans on hold . In August 2008 , Eileen Grimshaw received a call from Todd saying that he had seen Marcus in a nightclub in London , with another man . Eileen subsequently told Sean who initially dismissed it but became increasingly more paranoid and angry . When Marcus discovered that Sean made a pass at Tom Kerrigan , he punched Tom as he suspected that Sean had slept with him . Marcus later told Sean that he was fed up of Sean ' s jealousy and left Weatherfield . Sean pleaded with Marcus but he said an emotional goodbye to Eileen , Liam and Maria Connor and left for London , leaving Sean devastated . Sean and Marcus crossed paths again in April 2011 when Sean visited Dylan in London . Marcus told him that he often babysat for Violet and Jamie , whose relationship was going through a rocky patch . Violet agreed that Sean and Marcus could take Dylan out while she and Jamie sorted things out . When they returned , Sean had a row with Violet and when they left , Marcus told her to call him . In May , Eileen arranged a date for Sean with Marcus , and they began dating . Things seemed to be going well initially and Dylan even stayed with Sean and Marcus after Violet was badly injured in a car crash , leading Marcus and Maria to spend more time together as Dylan liked playing with Maria ' s son , Liam . When Dylan returned to his mother , Marcus realised that he wanted to be a full - time parent and looked into adopting but Sean ' s heart wasn ' t in it . Sean ' s jealousy also caused problems again when Marcus spent a lot of time consoling a colleague who was having problems with his parents after admitting to them that he was gay . Sean suspected that Aiden felt more for Marcus than just friendship and refused to believe otherwise so Marcus ended the relationship again . Needing somewhere to stay , he moved in with Maria and had a brief relationship with Aiden but had to end it when he and Maria realised that they had feelings for each other . Sean had hopes of reconciling with Marcus and was horrified to learn that he was now with Maria , as was Maria ' s boyfriend , Jason Grimshaw . Marcus and Maria were happy for a while and Marcus loved being a father to little Liam but Todd Grimshaw refused to believe that they were happy together and deliberately split them up , believing that Marcus just needed reminding about why he liked men . They had a brief affair and Todd arranged for Maria to catch them together . The pair had a brief relationship , but Marcus eventually realised that Todd was manipulative and only using him . Marcus left Weatherfield in July saying goodbye to Liam Jr . , and leaving on good terms with Maria who had forgiven him as she realised how manipulative and nasty Todd was . Quotes .
