The actress plays Maxine Minniver in the Channel 4 soap, who suffered domestic abuse at the hands of her former partner and father of her child, Patrick Blake (Jeremy Sheffield), and has been trying to move on with her new boyfriend, his long-lost son Dodger Savage (Danny).
But Danny is due to leave Hollyoaks and in his final week Dodger is kidnapped by estranged twin sister Sienna Blake (Anna Passey), while his own psychotic brother, Will (James Atherton), kidnaps Maxine and his other love interest, Theresa McQueen (Jorgie Porter), leaving him time to save only one of them.
Nikki said: "It's a really big week - there's going to be explosions and kidnapping and fires and fights. I love filming anything like that. Hollyoaks always puts 100 per cent into those scenes.
"Will Dodger follow his heart or his head? Which one will he choose? The viewers like Maxine and Theresa so I think they'll be split on who they'd like it to be."
She added that she was sad to see Danny go: "It was really sad, especially his last day, I was devastated. I'm really proud of him that he's taken that leap of faith, but selfishly I am devastated because I loved working with him. Everybody loves Danny Mac."
Nikki is nominated in in the Serial Drama Performance category at next week's National Television Awards.
