Once they are gone again I continue, "They've seen me with you now, they'll be looking for three ponies, not two. I could walk away right now, but if either of you get caught you could tell them about me, and then I'd be in an even worse scenario. So for now we're stuck in this together." I'm pretty sure this is related to either Changelings or crime, and in either case I don't want to be involved further by these two getting caught.
