The way P has been entangled in SaiRats life by making her a surrogate, She can never really leave them in the truest sense. She is now forever attached to Vinu.
Only her death can release them freely of her.
Or the other option is to make her mentally disturbed. That would negate all her importance for everyone. For BK, P would become another Devyani. She might get sympathy and care but no love.
A cancelled P... with or without marriage and her sense back in place will forever meddle in their lives.
With Sais entry now, her situation is totally "haath main aaya lekin munh main nai gaya"
