What Owen said below. He’s told me he wants to help the Order, and he could be on the level. He has reason enough to hate the Death Eaters, but like Jasper he’s also allergic to the idea of going vigilante. And he has his younger brother at Hogwarts to think about. He could be a good ally to have, Yaxley could get trigger happy about his firing threats again if we keep not chasing down the Order and kick Owen and I to the curb. Dawlish at least toes the line.
I personally want to trust him as an ally, but I’m incredibly biased in this respect. He could be playing me.
