<P> Dennis and Sharon return as a couple, after several months away and demand to see Den . Dennis sees through Chrissie's story that Den has left her for another woman but drops the matter to spare Sharon's feelings . Dennis and Sharon go on to marry, and following this, they learn that Sam Mitchell had exhumed their father's body from his grave in the cellar of The Queen Victoria public house . Den was murdered by Chrissie after she, Zoe and Sam confronted him about his manipulation of lies regarding the three of them (Den had tricked Sam into selling him The Queen Victoria). Chrissie had also lured Sharon back to overhear Den's confessions so that Den would lose the one person in his life that he truly loved . Den attacked Chrissie and Zoe hit Den with a doorstop to stop him . Den then grabbed Chrissie who delivered a fatal blow, leaving Zoe to believe she had killed him . The three women then buried his body in the basement . Dennis and Sharon bring Chrissie to justice and sell The Queen Victoria back to the Mitchells, apparently concluding the Watts / Mitchell feud . </P> <P> On Christmas Day 2005, Sharon is admitted to hospital with suspected food poisoning, but finds out she is pregnant, despite the previous belief that she was infertile . They prepare to leave on New Year's Eve to start a new life in the United States . Sharon does not tell Dennis that Johnny has threatened to kill him if they have not gone by midnight, but she confides in Phil, who then uses Dennis as a weapon against Johnny . Phil tells Dennis about Johnny threatening Sharon and also that Johnny had murdered Andy . Although Dennis realises Phil was manipulating him, he takes the bait anyway and beats Johnny to the brink of death . Johnny begs for help as he thinks he will die, so Dennis tosses him a mobile phone and says if he can reach it, he will live . Johnny is able to reach the phone and instead of calling for medical assistance, he contacts a henchman to murder Dennis as revenge for his beating . </P> <P> After cleaning his hands of Johnny's blood, Dennis makes his way towards the Albert Square Gardens where the locals are setting up fireworks, to meet Sharon . As they lock eyes, Dennis is stabbed and collapses, dying in Sharon's arms . His last words are "we did it" in reference to their unborn son who was born six months later and named Dennis in honour of his father . It is later revealed that Dennis was killed by Danny Moon (Jake Maskall). </P> <P> In October 2012, Derek Branning (Jamie Foreman) blurts out that Dennis was murdered, not knowing that Sharon's son Dennis Rickman Jr (((Harry Hickles / Bleu Landau) overheard him . Dennis is upset after learning the truth of his father's death, as he was told by Sharon that his father was a helicopter pilot and died while saving others . Sharon admits to Dennis Jr that she lied to protect him, and although he is angry, he eventually forgives her . </P>
