Lister explained that his character decides to be "sensible" by putting some distance between Eve and himself as he does not want to mess up again after his "distaster" of a marriage to Lexi. He added that Carl is "not tempted enough" to cheat on Chas as he believes she is "the love of his life and he's decided to stay faithful to her – at least for now". Carl and Eve begin an affair; Chas discovers this. Pargeter revealed that Chas' initial reaction is to confront the pair but instead she decides to seek revenge as she is "very hurt". Chas begins her revenge by doing "little things" but later decides to "up her game and to start playing really dirty". Chas proposes to Carl as part of her plan, Pargeter said Chas "can't help wishing it was all for real". She added that it is important to Chas that Carl and Eve get their comeuppance. Pargeter said that Chas can not decide whether she will go through with her revenge or if she would instead forgive Carl and marry him. She added that Chas "geniunely thinks he loves her" and she loves him too. Chas lies she is pregnant. Lister said that Carl will be "gutted" if Chas goes through with her revenge plan. He explained that Carl was "thrilled" at Chas' pregnancy and he now wants to "give Chas whatever she wants – a big Christmas day wedding, anything to make her happy". Carl "wants to become a proper family with Chas and the baby. He'll be devastated if it all comes crashing down". He "realises his fling with Eve was a massive mistake, based on excitement and lust". Lister added that Carl felt Chas' proposal and pregnancy were "a great excuse to get out of the affair with Eve because it was all getting a little bit complicated", explaining that Eve "was becoming too much hard work".
