"As long as we understand each other." Alastor resisted the urge to smirk at the kid's gumption. "Very well, this is how this is going to go. You are going to use the Christmas gift I happen to know a very nice werewolf gave you to call Potter -- and only Potter -- here."
It was up to Potter the second or Dumbledore to call the Order. At this juncture, there was no purpose in calling any of the rest Lupin had told him were connected to those pendants when he asked for help with the tracking charms embedded in them.

"You will not leave my presence and you will not use official channels to announce your unauthorised presence, either. Once You've seen Potter is whole, you and I will take a walk down to the south exit to help in evacuating the crowd. Is that clear," he growled.
