1st of all if u listen to everybody's account of what took place at the awards besides biggie n em, they said big/pac never spoke wasn't even close enough to speak
2nd of all Pac said Puffy/Big was responsible because they shoulda warned him cause if they was on the west no way sumthing like that would have happened on his watch he said he felt set up by them not that they had him shot
Voletta Wallace did an interview saying that whole ordeal about blaming Biggie for him getting shot was a money-making scheme for Tupac to sell records. Pac knew Biggie had nothing to do with it.
Tupac was really upset with Biggie because he felt he neglected him when he went to jail. Back when Pac did "Keep Your Head Up" and "I Get Around," he put Biggie on the payroll by letting him perform first during his concerts.
So when Biggie was out there going platinum with Ready to Die, he felt the least he could do was call or visit him in jail, put some dough in his commissary, and give him word on who the Brooklyn niggas are that shot him.
Ultimately, Biggie didn't turn out to be as close as a friend as Pac thought he was. He says all of this in an interview.
