I think considering how close he is with Yaz and Yaki's legacy, having auctioned off 2pac's hummer and all that, there had to be some kind of a connection, as Yakis mom would have remembered and knew whether he's bullshitting as he claims he hung out with her, Yaki and PAC back in the days.
In my head I though they probably met and hung out, but I am not sure to what extent they were actually close. Noble wasn't too close to Pac, and wasn't there for long when he was alive either. That said, even the group "Thug Life" was temporary, with 2pac saying he killed Thug Life and those people are dead to him after mere months, reasons unknown. 2pac had a lot of people around him, on and off. They often didn't know each other. And whether he was in any way close with 2pac is very difficult to know for sure, especially with Candyman not talking much details. It might be either because it's shady or simply because he was a kid back then for sure. If he was a 10 year old kid and was around the family, you can imagine that 2pac would have treated him well, but like a kid, and even if the interactions were brief, to this little kid 2pac became a memorable idol. Also, It's not like the Outlawz did any more good to 2pacs (or Yakis) legacy than him, to be fair, so I'm cool with the guy.
