The pair were an item in the past but have both since moved on from the romance, as Darren is now dating Nancy Hayton and Cindy has married elderly millionaire Alistair Longford.
Cindy is due to return to the village later this year as her portrayer Stephanie Waring completes her maternity leave.
In an interview with Inside Soap, Dawson commented: "Cindy will be coming back. I think out of Darren's previous girlfriends, she's the one he's been most compatible with.
"And even though she's married to an older man, there's unfinished business between them."
Dawson also hinted that there could be trouble ahead for Darren's relationship with Nancy (Jessica Fox) after he and Suzanne Ashworth become parents to twins in Hollyoaks' 3,000th episode next week.
He said: "Suzanne and the kids have nowhere to live, so they end up moving into Nancy's flat. As you can imagine, Nancy's not impressed in the slightest. She struggles to cope and Darren's set to have a really difficult time juggling her with the kids. It might not be too long before that relationship comes to an unfortunate end."
