"Something's happened to Sunita. It's Weatherfield water," she said on This Morning. "It was quite shocking though as I read the script. How would I move and be that girl? Maybe she's read [50 Shades of Grey]."
Delving into Sunita's mindset, Gulati explained: "She's had kids and she's with a man who doesn't really care. Then she finds a man who really wants her.
"She does feel rejected by Karl. [Dev]'s just smothered her again. So it's all very complicated for her, and she just feels like, 'I need something. I need to go out'."
However, the actress concluded: "She takes an option - the maddest and biggest option of Sunita's live. I thought, 'Wow!' She was very drunk at the time."
Gulati added that Sunita's decision to stay with Karl is an example of "momentary madness" which sums up her personal "crisis".
