You answered your own question in the beginning I mentioned this in another post...this is just to calm down fans - whatever they showed recently was obviously very triggering especially V's dialogues so now of course IVs will come out to put a "positive spin" on things and actors will give their "personal" opinions which not surprisingly matches what the shows narrative is lol
Another thing I think audience will have to accept is that P will be considered vinus mumma that will never change....shes never going to change from mumma and downgrade to Aunty - so going forward the story will be that Vinu has 2 maas and it will have to be accepted....
If they are basing it that she gave birth to Vinu then thats definitely incorrect but basing it that after adoption he accepted her as mumma and raised him ( no matter what her intentions were he doesnt know that) then they will still continue that P is mumma - As a audience we may not believe it but narrative wise they showed P fasting for Vinu going bare foot ....doing over and above for him, going as far as bringing sai into their lives to cure him - through the story or shows narrative she did this all for VINU, for audience we saw she did it to get close to V - what the story was trying to show didn't get accepted by fans but they are still continuing with it ...
If I can play devils advocate again for p for a bit in regards to V- based on what they are trying to show not what audience sees
P was genuinely changed she accepted the deal marriage initially for Vs happiness and at first she was fine with it - they showed even she was uncomfortable with trip talks etc...basically she buried her obsession but it wasn't gone! but the family kept telling her its her right to move on with him...she has to push him blah blah...and V then gave her slight hopes with taking "friendly " trip etc so her obsession started to creep in then in KK V gets shot and her TRUE feelings come out where we see her obsessive behavior of kissing him and all that...and from there V started feeding this same obsession (unknowingly as he thought she changed) and she starts to get hope he gives her assurances and her obsession comes back fully and now we have this result lol
but going back to your original post
this was planned from the start which is why P was never Aai the 2 mummas was destined...I knew it when Sai herself after Vinus birth gave the 2 mummas dialogue...
so basically the actors are going to give an opinion that coincides with the narrative of the show
not surprising at all
