Etch's Links
Etch feels cautious around Ditto, due to their tricky nature. From Etch's point of view, Ditto has humiliated/one-upped them a couple of times (The infamous bar scene), and this will not stand for him. Etch may even say he feels rivalry towards Ditto.
Quite scare of him, frankly. Honestly wish they could be friends, but it's hard. Really likes their glowy bits though.
