One of the biggest debates with Dragon Ball Daima is whether Glorio is a traitor, so I'm going to say my two reasons why I think he is not.
1- Despite his apparent alliance with Arinsu, Glorio remained hidden listening to his conversation with Gomah, if Glorio was allied with Arinsu, he would not have had the need to hide, since at that time Arinsu was pretending to be at Gomah's service.
2- Although Glorio knows that he is weaker than Goku and Vegeta, at no time has he shown concern about the power level of both, on the contrary, his concern has been because he thought that Goku and Vegeta could lose.
These two things make me think that Glorio is either an ally or has his own motives outside of both Arinsu and Goku.
