Sunita finally returns home to Dev (Jimmi Harkishin) next week after being rejected by secret lover Karl Munro (John Michie). She then attempts to fix things with Dev by making a hasty marriage proposal.
Viewers will see that Dev agrees to re-marry Sunita, but whether they truly can get back on track remains to be seen.
Asked why Sunita reunites with Dev, Gulati told Soaplife: "Because Karl doesn't want her. Yes, she got bored with Dev and the way he treated her, but maybe she can see now that the grass isn't greener. She's had her heart broken and now she needs some security."
However, Gulati added that Sunita is still in turmoil as news of her engagement spreads.
She said: "The funny thing is that Dev announces their engagement in the pub and instead of making her feel brilliant and vengeful, she feels awkward around Karl. She's obviously not over him. And is he over her?"
Coronation Street airs the proposal episode next Wednesday (June 20) at 7.30pm on ITV1.
