Dudes love to gossip.
Truth is, Faith fukked up by even booking sessions with Pac. She should've known better. There's no way around that, or acting like that wasn't just a dumb move. But everything else is just people speculating based off what was said on records. E.D.I. was with Pac damn near daily, and said mad times that he never saw or heard about Pac doing anything with Faith away from the record, and that Pac would just "say shyt" to fukk with people. He said Pac was doing the same thing when he was going at Nas. But that Pac was a huge Nas fan and was rolling around playing It Was Written nonstop, and actually reached out to Nas to tell him that he went at him on the album, but he was a fan and wanted to squash shyt.
Hip Hop is mostly smoke and mirrors. A lot of shyt is said and done for shock value, or to spark shyt with people you don’t like personally. But a lot of these stories stay alive 20+ years because the fans sensationalize what they either hope happened or just heard on a record.
