From what Frank says, it could go either way -- but he doesn't seem hopeful for an out and out victory.

You'd need to be in fighting shape to make it worth the risk of sending you along, and Apparating tends to be tricky with you under ideal conditions, but your presence might rally the troops, as it were. And it seems like everyone else is bloody exhausted too, so it might even the field. We could use Turner and whoever he's got who has enough energy left as well.

If you do come, Remus stays behind. For Bea.
