18: "Over so quickly? Again. Nothing new."

Android 17 and 18 are walking through a destroyed city before 17 stumbles upon a weird looking instrument

17: "Oh...?"

He picks it up. Inspecting the ocarina

18: "What's that?"

17: "It's... Mystical?"

18 smiles at this

18: "Heh... Simply magnificent."

17 smiles as well

17: "I'm definitely keeping this-"

???: "Wh-what?! What do you think you're doing?!"

The two androids look behind them to see a strange figure standing a top some rubble. He doesn't look very pleased with 17 holding the ocarina

Tapion: "Give me back my Hero's Flute!!"
