Things go awry when Den discovers that Sharon and Dennis have resumed their affair, and in order to split them up, Den persuades Zoe to lie that she is pregnant with Dennis's baby. Unwilling to allow Dennis to leave his unborn child, Sharon leaves Walford with Vicki leaving Dennis and Zoe unhappily together. In apparent retribution towards Dennis for inadvertently being the cause of Sharon's departure, Den manipulates Zoe into having sex with him so she can get pregnant and pretend the baby is Dennis's; when Dennis catches them having sex, Den appears pleased.
