I don't know why but I have soo many suggestions today 😊.
I was just thinking of another scenario. Anne is close to Dev. What is Anne confides in Dev about what happened between her and Arjun? That was Dev can know that Arjun is against Maan and make peace with him. He can also blame Maan for everything and tell Arjun that he did something to force him to divorce NT. If Arjun and Dev tie hands and work together to destroy Maan taking advantage of his vulnerability now?
At some later more complicated stage Arjun can figure out that Dev is the culprit and that he was just using him and switch sides to help Maan and Geet. But till then, Arjun + Dev against Maan
Also, what daadi and Anne did to Geet was very unfair when it came to Dev, They encouraged him to stay with them and forgave him without understanding what that did to Geet. I really hope Anne finds out now that she is pregnant after her kartooth with Arjun and Arjun refuses to marry her. And that can be when Anne confides in Dev, Since Dev does not care about anyone, he wont care about Anne either and will jst work out a deal with Arjun to bring down Maan. I want daadi and NES to understand the pain Geet has been out through because of Dev.
