I hear what you’re saying with the crying wolf. But I have to disagree here. There has always been a clear distinction between when she does something just to one up Aryan and when she doesn’t. During their Haldi and when they arrived at Rathore mansion after their fake wedding, Imlie had all the opportunities to wreck havoc in retaliation against Aryan. But she didn’t make use of them solely out of consideration for Narmada aunty and Arpi didi, much to Aryan’s confusion. In the scene where he asked her why she didn’t return tit for tat, she told him that she considers Narmada aunty and Arpi didi her own and therefore, will not hurt them simply out of her spite for him. So Aryan very clearly knows that Imlie would never intentionally set out to do anything to make them look bad.
Well I too felt it odd at first.
But then I realized it's the classic Sher Aya example.
3 times a thing is said or done by you, 4th time it will be automatically associated with you. And then if you say I didn't do it! No one will believe.
Imlie's open distaste is costing her credibility in a very sublimal way. And today was the start of it. Even if his love remians unhinged, he's a human afterall. And emotionally vulnerable to her. So her words of hate will somehow effect him. Today I felt like it's the start of that track. He unknowingly expects any sirphiri harkat from her.
