The actor's final scenes in the role will air later this month following the decision to bring the character's story arc to a close.
Speaking to All About Soap about his alter ego's exit, Bergin teased: "His last few scenes are really emotional, and there's one final twist to the tale!
"I can't say whether Danny leaves Albert Square alone or with another character in tow - but his exit sums the character up perfectly."
Asked whether viewers have seen the last of the schemer, he replied: "Who knows? I've had the best time on EastEnders and I'd love to come back again sometime in the future. It's good because Danny's story is left on a cliffhanger, so he may well show his face again in Walford."
Bergin has previously had small roles in Doctors, Trinity and Five's Minder remake.
