Quote (TheWatcher)
Tupac thought the beginning of Nas's verse on the Message was directed at him when really it was Nas going at Biggie.. Biggie knew this but Pac didn't so he proceeded to make 'Against All Odds', they squashed the beef before Pac died and he meant to remove what he said about Nas from the album but died before he could do that.
he also dissed The Firm too because they were on Dre's Aftermath label, which automatically means 2pac has beef with them. so i don't think Nas and tupac would have settled any beef, if they had it wouldn't have been for long. there's that recently released 2pac acapella where he's dissing the firm, dr. dre, mobb deep etc.
