Oliver/Grace
I think that communication in the Order is important. On all sides it doesn't seem to be flowing very well, and I can understand why people were upset that they weren't told or included in the decision-making early on. We're all figuring this out as we go, but this will always be a charged issue, we've all been affected by Death Eaters in different ways.
I won't lie, I don't trust a Death Eater no matter what they say. But I trust you and this is something the Order needed to confront. What are we going to do when this is all over and we have all these Death Eaters? You're trying to help Oliver, you should feel proud of that.
