"Yes, I am a human, what's it to ya?"
The alien looks like they're frowning, but it's hard to tell what they're doing due to the fact that their mouth is very buglike. "You are rather insolent, aren't you?"
You remain silent, and after a moment the alien motions for another alien to take action. The second alien, which is taller than the first, says, "Come with me." and lays a hand-claw-thing on your shoulder to stop you from running away.
You follow the odd creature, but rather reluctantly.
