As first revealed last month, Darren soon decides that a surprise Valentine's Day ceremony would be the perfect romantic gesture for girlfriend Nancy (Jessica Fox) - so he starts plotting the event in secret.
Dawson told Soaplife of the storyline: "He's got The Dog back, is content with life and thinks, 'Why not?' He wants to show Nancy how much he loves her and thinks a surprise wedding will do that."
Asked whether it's a good idea, the actor replied: "I don't think so. What does Darren know about weddings? Nancy would want something classy and Darren doesn't have any cash. He'll have to call in a lot of favours, but he hasn't got many friends.
"But this is Darren for you. He comes up with an idea - a bad one - and has to see it through even though he could end up upside-down in mud."
Hollyoaks launches the storyline later this month.
