But before you get there, I attempt to communicate with the alien. They have superior senses to that of humans, and he/she/it/whatever notices me. I tell it that the orb is a fake.
It doesn't seem to care. I say that I was sent to say the deal is off.
Nothing.
It seems irritated (probably because I keep trying to tell it stuff even though it doesn't know me). It walks off somewhere, probably to get away from me. This is a huge alien black market; good luck finding him again.
