It could be the skeptic in me but I think the following are some of the reasons
1. To show how dynamic and able Navneet 🤢 is, because I bet Sachin or Jihan stood no chance in the beginning of the contest and still doesn't. Sachin has shown previously how incompetent he was, and this time presto he won, coz Navneet the pasta master was with him. What better publicity for Navneet ( and hence proving he is a top contender) than doing it this way. Should shut the naysayers who say Navneet has reached so far based only on luck.
Okay, it can be argued that Sachin made the best dish on the day( but like I said I am a skeptic)
2. To show how mahaan Ripu is, I suppose everyone knows by now that I am no big fan of Ripu but seeing him interacting with Khoku has really warmed me. It has also demonstrated how Khoku was struggling without his help. Poor girl should have chosen something she was comfortable with rather than listening to Ripu's arty-farty ideas. So now we have further cemented Ripu's mahapan( TBF I think he was genuine) and also shown that Khoku is not as good as many of us think here. Editing ka kamaal. Although I still think she is very talented but not confident or vocal enough to push her ideas forward.
3. To show how worthy Doyel is- as her simple chutney is what made Devayani's dish. Forget all the hard work that went into making those muffins. It's the chutney that clinched it.
4. To show how boastful 'i dont eat chicken but I cook the best chicken' Happy is.
I feel, they want some candidates back in and surely one of them can't be Sachin ? So is this all genuine or is there something behind all this. Or is it show us that the judges aren't biased and they even chose Sachin who was the weakest amongst the lot. This can go in circles, so I am ending it here!
Like I said, it's just my opinion and I have too much time on my hands.🥱
