If anything, now that he knows that the Children of the Watch are a fringe cult, and not the majority of Mandalorians, I could see him eventually abandoning it's precepts and joining up with other Mandalorians.
So if like me - you only watch the live action shows (and that will be a lot of the audience) - that scene plays in a slightly different way - it's not clear why we should trust what these unknown characters are saying.
