>Okay then, here's my idea. You use your noble phantasm to hide your presence, then when I get back into the car, you open and close the passenger door as though you'd gotten in with me - pretend we don't suspect they're watching if they actually are - but instead of getting in, you follow along from outside. When we get closer to... wherever it is it we're going, you can range around slightly and see if you can get an aim on whoever it is calling us out here while - from their perspective - you should hopefully still seem to be a passenger. Maybe they can't observe the difference and this is all unnecessary, but we seem to have nothing to lose by trying - if I plan to follow their instructions, anyway.
>And I think probably I should. If it's a bluff, then they're still out there, possibly still able to tap into my phone and any plans we make with it, and will probably set a better trap next time. Maybe we can seize this chance to surprise them.
