Once he's finally lost that terrifying cactus, Omi goes on a hunt of his own for the source of the arrow that hit it. That was too reckless! A rooftop sniper himself, he has a pretty good sense of about where it must have come from based on the angle and location of impact. He climbs up to the roof of the most likely point of origin and spots a young kid who looks somewhat familiar.

"Wait a minute!" He says in a scolding tone. "What are you doing up here?"

As if that weren't obvious.
