I wonder how these mystery men are connected. We've now got Sahil in the mix. Maybe Sahil and Akash (Vinnie's brother) are actually working together? Maybe Akash snooped in on Vinnie's friend circle and found out about him- and decided he's likely to help out? Sahil wants to turn everyone against Sanju. Akash wants to torment Vinnie- that includes breaking up the BFF triangle. Both have a common cause. But it's a difficult question- who's more malevolent- Sahil or Akash.
Although there's no proof, it's an easy guess that Akash called Tattoo Man over to their house to kill Vinnie- which didn't happen. He also seems a little scared of the BFFs for some reason in his appearance, post-Tattoo Man capture. Tattoo Man is connected to Daljit- oh my, Akash found a way to Daljeet? The promo has a voice-over "Vinnie, bhai ko laptop do"- and he's often seen on a computer- hacking? Anyway, I hope to see more of him in later episodes.
