From reading today's update, there are two good things bajaj has done:
One he has left it to destiny, some people might see this as passive, not fixing the problem hoping it to fix on its own, but sometimes, problems like these just need time to heal, when he said to anurag, its okay i don't need you to patch my relation with prerna, he was asserting to him that his love is strong enough to overcome this test, and that he knows prerna will come around.
Second, it was wonderful that he accepted Tanisha, without fear of Prerna, when you make the decision (whether you are aware of it or not), to have children, children must come first before anything else, in terms of priority of relationshisp, including that one with ur wife.
Like Manasi pointed out, Tanisha is becoming more of a round than flat character, before she was just the bitch who ruined kasak's life, now she is having way more shades to her, by showing care for bajaj and vineet, and by not supporting shravan when he was wrong.
I wonder what the future has in store for shravan, tanisha, and kasak, thier love story has been stalled, though i don't miss it, i wish they could tend to it a bit more regularly before adding more twists and turns, but i guess that's how life works as well, twists and turns are always around the corner, whether you want them or not, or whether you have deal with previous ones first.
