Before AOTC, Blackie takes a leave of absences from the Jedi Order, but before leaving, Windu gives Blackie a letter.

And then when Blackie is at his homestead, he opens the letter, where Mace wrote to him about how he was proud to have him as a Padawan and that if he were to ever die, then he is take Windu's saber as his own and wield it with pride along with his own.

So then in the first film, Blackie guest stars in, he'll show the team this letter after he tells them that Windu's saber now belongs to him
