We know that Karan Kundrra is the chosen winner of Bigg Boss this season.
He's topping Ormax and YouTube polls. His physical violence are given a pass with just a slap on the wrist. Host continuously coaches him to improve his game, because they need their winner to look like one to justify his win.
Guests like Raftaar and Neha Dhupia who worked with him in Roadies also come to boost him up.
Due to this, I think Teja and Umar would become the sacrificial lambs. If Karan is the winner, Teja and Umar can't be first and second runner ups. Because they all are more or less on the same team.
And a whole group of friends on top 3 won't look good. Bigg Boss needs a rival to pit against Karan, and they've chosen Pratik for that. They're selling this guru vs chela narrative and I suspected from the start that this rivalry was the main planning of Bigg Boss which didn't work out well.
Most likely Pratik would be in top 2 with Karan to sell the whole rivalry thing.
Teja definitely won't be in top 2 with Karan even if she's the second most popular contestant after him. Because Bigg Boss is not going to put a couple in top 2. This means Teja is not going to make it to finale. Makers would make sure that she gets evicted before somehow.
Even Umar can't be in top 2 with Karan because it's again two brothers together. He ain't Bigg Boss favorite either. He's an easy choice for makers to evict.
So I think Karan, Pratik and Shamita would in top 3 respectively. Bigg Boss also has to somehow make Shamita reach finale and give her a respectful 3rd position.
But that won't be possible with Umar and especially Teja as they would definitely get more votes than her. If Umar and Teja want to be finalists, then they have to go against Karan. Being in his shadow, they can't go forward.
