The actress was asked about Helen's plan in season 2, to which she replied:

"I want to kill Dani. I don’t think it’s OK that she tried to f**** my husband and kill me on Christmas Eve."

She added:

"So [Joe and I] are having a very funny text line at the moment where I’m basically saying, “Let me kill Dani.” And he’s like “Errr.” I’m going murderous, and he’s like, “No, wait a minute!"

Considering Dani's ambition to become a Black Dove, she might still try to eliminate Helen and end up getting killed. Or, it might be possible that she joins forces with Helen and learn from her. Since her storyline isn't confirmed, it would be intriguing to watch Dani's fate in Black Doves Season 2.
