I hope you are having a good beginning of a new year.
First of all I am glad that Kanjali is still in the show and ready to dance their way into the coming weeks.
I thought that Arjun was being more sympathetic towards kanjali in their performance against chetan and lavina. Truthfully, I didn't see too much dance in chetan's dance, just sword fighting techniques. Chetan is a better dancer than lavina because he is more capable of giving more energetic performances.
Kanjali on the other hand had no props, just pure dance steps and that is what gave them an edge in their victory against chetan and lavina.
I think Arjun gave them a 9 because he wanted it to be a tie breaker b/c chetan lavina got an 8, 8, 8 and kanjali got 8, 8, and 9 so kanjali only one by one point.
I am glad that Arjun gave kanjali the benefit of the doubt and gave them the extra point to win.
Also I think that Kanjali is Arjun's favorite jodi, it's just my own personal hunch as I have been watching almost every epi in this show.
