Throughout November and December 2013, Declan began physically abusing Megan by hitting her across the face on numerous occasions. Eventually, Katie witnesses one of Declan's attacks and sticks up for Megan, despite Megan saying that it was just a misunderstanding. On Boxing Day, Megan enters a fire at Home Farm, believing that Declan is trapped inside, but she is unaware that he caused the fire and left earlier with Charity Sharma. Megan becomes trapped herself but is later freed by the fire brigade. Megan isn't very pleased in April 2014, when Declan reveals he is engaged to Charity and that she is pregnant with his child. They plan to get married on 15th May 2014, although Charity's former boyfriend and cousin Cain Dingle and his fiancée Moira Barton also intend to marry on that day. Only Megan, Robbie and Charity's son Noah attend, as the rest of Charity's family are at Cain's wedding. Just as the registrar pronounces them husband and wife, Megan sounds the fire alarm, which infuriates Charity. When she finds out what Megan has done, Charity slaps her and a small fight ensues, although Declan stops them.
Unbeknownst to Declan and Megan, but Charity has her pregnancy terminated as she never wanted a child. When Charity is having an argument with Megan, and Megan accidentally knocks Charity to the floor, Charity uses the accident to fake her miscarriage. Megan, becoming ever more guilty, reveals this to Declan, who shouts at her and throws her out. Megan then begins a relationship with Declan's enemy, Jai Sharma, and becomes business partners with Leyla Harding.
