Bellatrix reclaims her hand without sparing that courtesy so much as a thought, dark eyes scanning the room about them, but it's not a matter of taking in the surroundings - she's simply trying to determine whether anyone else is there. It would be so simple as putting the mark to use again, but if they're already gone, she wants them to stay away - for the moment, at least.

Her gaze settles upon Rodolphus once again, and the pin is spared little more than a cursory glance before her eyes lift to meet his, bright with renewed excitement. "And the last you remember?

After she hadn't been there to learn it for herself, anymore.
