It's just that Pragya is not too close to him now (I mean she is not biwi, GF, lover).. so his reactions about her are not as strong as before. He is not told anything too bad about Taaliyah either.. hence his reactions aren't that powerful either.
But see he still beat up that accountant guy recently, he still broke into kidnappers etc.. his comedy is a bit less now.. because no one is there for him to take digs at lol.. I mean Pragya is too sweet with him.. all are behaving according to him.. even Taaliayh don't stress him out much. So he is enjoying the peace. I don't think it will stay like this for long.
