This does seem a bit different than traditional proms in that sense.
As much as I would like to assist you, Miss Forbes, I am afraid that I have already asked Alexia to attend with me. She has been on of my closest friends for over three hundred years and has what I believe you would call dibs. And, I think we can both agree that, in the event Niklaus should arrive here, it would be best to avoid anything that might give him the wrong idea. His jealousy often overwhelms his reason. I apologise.
