[X] Explain you aren't a one of the red court
-[X] Attempt to convince them that you aren't something that feeds on mortals and today you're just making use of the airport, not going after the people in it.
-[X] [Stunt]: Snorting, Molly all but rolls her eyes " You should get your eyes checked. Dark I may be, but a leech I most certainly am not. A catfish, maybe a heron depending on your metaphor, but not one of those squirming little creatures."
—[X] Taking a more serious tone, she continues "Out of sincerely held respect for your organization I will allow you to test my nature with items of whatever faith you follow, but you of all people should know that
choice makes monsters of men before nature does. I have no taste for and even less interest in ending mortal lives"
Play up the offense, don't get into anything too hard to believe, and avoid mentioning our business.
I'm talking about this part here:
I know you were.
She's prepping to do that to open up combat, you're ordering her to do something she's already planning on.
Even past that it still has to be a deliberate act taken on as our servant. If Molly buys lunch at McDonalds MiS doesn't hit the person taking her order and any of the kitchen staff involved in making it even though they literally took her order. When we were working for Odin asking a fey to pass us a wrench wouldn't have applied it to them either. In both cases the other people involved would be working for someone else.
To apply MiS we need them to accept a role as our servant, and to take orders because we gave them even if they have other motives for keeping the job.
Or that's my understanding of how it works anyway.
