Yeah, I think he is. He stood up for Gautam when no one was and even in livefeeds, they are generally hanging out together.
I think Pritam gets influenced by certain people too easily. Karishma and Puneet used to have a hold on him, but its being replaced by Praneet. Pritam was all gung-ho about Gautam being captain after talking it through with Gautam and Puneet, but is now focused on becoming captain himself after talking with Praneet.
But despite that, I think he's one of the few people in the house that genuinely gets along with Gautam and isn't just doing it because of P3G image. Well probably a little bit due to the P3G image, but not like Puneet and Praneet.
Everyone else is the house is only nice to Gautam because of Gautam's popularity outside of the house. It's 100% obvious that Praneet and Puneet generally don't like Gautam too much. Dimpy is only with him because she knows how popular he is outside. Same with Ali, but Ali also tries to be okay with everyone. Renee was also good with him because of that initially, but she's more toward Upen because she likes him LOL. Karishma, Diandra, Arya, Upen just don't even like Gautam so they don't even try. Sonali went to Gautam initially because no one else would come to her/ P3G and when it was becoming into a full friendship, she went to Upen and get Gautam distanced himself from her because of Dimpy and she got pissed so she's distancing herself from him.
Bottom line, Pritam and Sonali seemed like the only two who would've hung out with him even when P3G was popular.
