not necessarily. They shoot ahead and plus he is doing promotions for some stuff just like he did for boss. The show didn't miss out on him too much. I saw someone pair his interview here on how he said he will balance tv, films and web series. So when the track doesn't need him he is out doing something else. I think it's good that ekta gives him the free reins to not be tied down to one thing only. She most definitely isn't looking to recast bajaj like with komolika.
He cannot be tied down he will leave the show then. This flexibility is working for him a lot which is a good news
