And Locus isn't getting paid to kill them. We don't even know if he's getting paid to capture them anymore. He could be just getting paid to fight the war now, or to retrieve more artefacts or whatever's in the crate.

It might be a hard decision for Grif, maybe he thinks his friends are dead. Maybe in a battle he loses heaps of soldiers. Maybe he has a falling out with Tucker, or Kimball, or Simmons and is captured by Locus. And Locus offers him a chance to leave either in exchange for secrets or just to get him out of the picture. He's not perfect. Nobody's perfect.

And maybe it's upon realising he's all alone at Valhalla that he decides to turn back to Chorus. - maybe with the UNSC if he can convince them. That could be his return and the way the New Republic win the war.
