You were friends with a strange guy named Zen. And he is acting quite weird. For example, going out late at night in the forest, or talking in another language.

One night, you decided to follow him, and when you did, he wasn't the same Zen anymore. His short black hair turned silver. So did his brown eyes.

Once he noticed you, Zen immediately flushed red, as his long ears were visible. He was an elf.

What do you do or say?
