The first time that Tejasswi said this...was way back I think. And that time this seemed as silly and impossible as anything to me. Even now, I don't think I would've thought much of it if all these arguments didn't happen between Shamita and Teja. But looking at all of these things, I feel like there is some chemistry/ tension between Karan and Shamita.
TBH I don't think Karan likes Shamita. He only mellowed towards her because she's a favoured contestant. I remember there was a WKV, one of the firsts, where Shamita was clearly favoured and Karan became very very polite with her after that. He just avoids any fights with her. And maybe appreciates her maturity etc but I don't think he likes her. For that matter, I don't think he likes Teja either. Especially not anymore, it's all for the game now.
But Shamita. Why does she keep going back to Karan? See Teja and Karan are together, and probably most of the day so Shamita spends time with her OTT friends, but I see that she is very competitive with Teja, which could be because she's favoured on the WKV, but then why go to Karan, only to annoy Teja? When you can spend the whole season without interacting much with Karan, why has it become so frequent in the last few days? She got Bapat, Neha, Rajiv among others in the whole season to be with. Now, the OTT guys are there, but I feel like she's not as occupied with them because I don't see any feelings or emotional connections with them. So, she's got attracted to Karan, which may have been from the starting probably but now she gets to act on it. She likes these little talks in the corners with him. Likes to undermine his "immature" girlfriend, likes the attention he gives her, cuz out of all the guys, he does give off the most desirable vibes. Prateek is annoying and shrilly, Nishant is weird, Bichukle is nothing. So, Karan it is. I think she likes him and that vibe is pretty evident between them. I wouldn't be surprised if something more along these lines came up later.
Also, I feel like dominating women like her settle with gentlemen like Bapat but are always attracted to even more dominating men like Karan. Only that they cannot get along that well together because of their nature. Let's see if something cooks up in this sense for them. I hope it does. Karan and Teja are just waiting to break up.
