I agree.
Everyone is the house has their issues, and Gautam is no exception. He's weird, like straight up weird, snappy, footage artist, etc. But unlike the other contestants, he's also shown some really amazing, admirable traits.
I LOVE how straight up he is. He tells it like it is. The whole Arya-kutta thing just proved it. Whereas, the other housemates, especially Diandra (Puneet is already called out too much), bitch SO MUCH about everyone and when they're cornered about it, they feign confusion and pretend they never said anything. I'm especially miffed with Diandra over this. The girl is the biggest manipulator in the house (even more so than Puneet I think). She instigates shit and then pretends like she never had a hand in it. Like she was the one who raised actual red flags in the Soni-Upen relationship by calling it weird, yet she gets off scott-free.
Secondly, like you said, he rarely keeps grudges. Fricken Puneet and Pritam backstabbed him. And honestly, Gautam knows that, he implied as much when he questioned Puneet during the captaincy task end. And Praneet is seriously going crazy on him. And yet he maintains his love for them. Even Karishma and Diandra. Hell, if I was in his place, I would've lost it with those two, especially Diandra. But he's totally remained neutral.
He comes across as a very sincere person, even when he's strategizing.
And of course, the way he's risen and stood tall in the face of adversity is legit inspiring. Takes so much mental power to do that. Honestly, I don't think I'd be able to survive in that house and calmly as he is. The entire house looks for ways to hate on him and anything he says is held against him. It's hell. And yet, he's still there, playing his game and behaving better than the other contestants.
