I dont want Sai also to be made bipolar. I want her dialogues to be clear about WHY she doesn't trust virat and what her problem is. Until now Sai has been very clear but Virat does not get it. So i hope they maintain her clarity in future too. I hope she will spell it out to virat- Her problem is pp. Her problem is that virat has a past n its difficult to not just accept that but also have his ex in their vicinity throwing taunts/jibes at them 24x7. Her problem is that despite seeing virats care for her, she doesn't feel as if he has accepted her out of love but that everything he does is either only an obligation for him or maybe out of habituation. So i hope that all this is clearly communicated to virat n that he tries to address all this before "leaving" to give her space. I think rather than a deliberate transfer requested by virat, just a mission/short duration away from each other after a conversation will help Sai introspect n come to the desired conclusion. It'll really affect Sai negatively if Virat abandons her deliberately. And that will be more of a coerced introspection. It'll be fear of losing her only family if hes cutting ties with her with no clarifications about his feelings.
She should get the full truth from virat before any realization.
If she suddenly realizes she loves virat after he moves away without him ever telling her all that he feels- about past n present - about pp vs Sai - then it'll be really kinda silly.
In the original KD, i feel like Sai never really got a good sense of how Virat really felt about her nor am I sure if Virat understood that she is insecure n scared, hurt n pained .
