Leanne's world is about to be ripped apart as she discovers her husband Peter's (Chris Gascoyne) affair with Carla Connor (Alison King) in dramatic scenes at Frank Foster's rape trial.
Danson told The People that she is excited over the latest heartbreak faced by her alter ego.
"She has had a dramatic couple of years but I'm not complaining," the actress explained. "The writers have come up with some amazing stuff and I trust them completely.
"It will be interesting to see what she does and how she copes with the situation with [Peter's son] Simon. She is a survivor, though, so whatever happens, she'll get through it."
Asked whether Leanne could forgive Peter, Danson replied: "Some people may think she should, but I don't think she can - even though she cheated on Peter with Nick.
"But it may not matter as Peter also has to make a choice between her and Carla. The affair has hurt Leanne incredibly and for it to be exposed so publicly is awful. There are lots of different twists to come in the next few weeks."
