You help

You decide to help take the inhibitor off. It takes you a few minutes, but you finally manage to remove it.

The alien stands up and bows. "Thank you, kind sir, for your help. What planet am I on?"

"You're on Earth. As far as I know, humans are the only ones in the universe."

The alien seems to smirk. "Obviously not. But since you have been so kind to help me, I am in your debt. Would you like to know more about my kind?"
