Alastor snorted. "Why doesn't that surprise me?" Now that he was truly awake, the fact Black did have this information was even more interesting to him. And, really, that could be the only explanation for why he wasn't exploding at being given orders.
They needed an information network as efficient as Black's. Or, they needed Black's.
The idea made him pause. What Black was asking was...tricky...and that was just in getting the others to agree with it. But, the young man actually had a point. If they could be seen to take this sort of action so soon after that attack and Potter's death, it might convince more of them on the outside to start resisting the regime. As the young woman in question was currently free and not imprisoned, it held less of the risks something like one of Potter's prison break scenarios would have.
And, if they helped Black, perhaps they could get him to help them.
"That's a tall order and you're making a lot of assumptions. Still, you have a good point. I'll need to talk to the others. So, I won't make any guarantees." Especially because he was not taking orders from Black! "But, I'll see what we can do.""
