I feel we need to make some allowances for the new Mrs Rathore here. She is like a recovering alcoholic who tends to fall off the wagon if her support group is not around aka ASR. Now since knowing about Aryan's revenge plans she is a bit directionless. Aryan and his udhar's are driving her up the wall. I believe for first time she had felt equal in a relationship with ASR and somehow, finding out that there is a chance he had been not 100% honest with her from start makes her feel unsure. Ironically, she is doing that same thing to ASR that AKT did to her. Doubting his intentions with her based on something her ex told. To add to that ASR getting Aditya wrongly arrested miffed her no end as she believed ASR to be harsh but honest businessman.
But her defense for Aditya though is irritating to us is not unfounded. She has known him to be an honest journalist. She has been inspired by him in past. He had guided her for a real long time. Longer than ASR. I personally want Aditya to be culpable for sensationalizing and wrongful reporting of the news as Aryan belives because that is a best way to take the story forward. But as character Imlie has to find it on her own. And to do that she needs to be galvanized into action. This time her motives are not purely just to save Aditya or the Ts. Because I think she is confident that AKT is innocent. This time Imlie's effort is for the Rathores. She wants them to close this chapter and move forward. And she thinks its only possible when she proves that Aditya is innocent. She is doing this to get ASR to give up his revenge and come back to living his life fully, rather than just to save the Tripathi family or Aditya. Though due to shows track record we all are thinking she is doing it for Aditya, I for one feel that Imlie is actually doing it more for ASR and Rathores. This time Aditya is just a means to an end.
PS: I know AKT has shown poor judgement as a professional since ASR came into the show. Eg: fight club sequence, page 3 coverage, humiliating Imlie with the obituary. But before that, has he ever been shown as reporting half baked stories? Just want a reference.
