See the point is that the promo is talking about events after the whole reunion etc. is done with......us point tak toh Adi will just be grateful to be alive and with Imlie.....baad mein aayenge questions about what SK did....and people like Didi will give hawaa to that, toh usse related ho sakta hai yeh jo bhi disagreement hai in the promo.
Didi will deffo try to play up SK's part in this in front of everyone and cast full blame on him.....uska guilt trip karne ki koshish karegi Imlie ko, manipulate karegi Adi ko ki dekho you do so much for Imlie and this is how her family treats you blah blah....and that is what may lead to a convo between them regarding that.
Ya toh Adi also genuinely is not thinking clearly cuz he's upset.....ya koi twist hai and he's just doing upar se dikhava to mess with Imlie and phir thodi der mein bol dega ki how could you ever think I would hold this against Dadda 😆
Didi toh apni ghatiya harkatein try karegi hi to bhadkao Adi against Imlie & SK. Adi as usual will listen to her gyaan & then go announce in front of the family why he is not going to hold Imlie & SK responsible with full on kaccha chittha of how many times Imlie & SK have forgiven him for his mistakes & SK did this only because someone tried to cause misunderstanding🤣. This is how he always reacts to Didi ka instigation. So I am expecting something along this line.
If Adi is upset over SK shooting him toh it will be momentarily only or as you said he might be just trying to intimidate Imlie & then himself explain to her that he can never hold SK responsible.
