If you think of Bani as an individual, I guess, she will. She will share the blame, realize she too played a key role in that ONS. And that will guide her to lets bygones be byegones. She loves him blindly.
On the other hand, she has placed him and her pathetic sis on pedestals...and their joint back-stab will definitely hurt. And if someone eggs her on (remember Roshni egging her after the PR confession?), she can do unmanageable damage to it all. And if Peabrain tells her its for the best that she leave JW, Pea and their baby alone, she will do just that. Again, she loves him blindly- and if she thinks thats how he's gonna be happiest, she will do that sacrifice act again...
GOW (God only knows) what'll happen...or shud I say Mai only knows? 😡
