(you are Male Knuckles meeting Male Rouge for the first time. Aka Rogue. He's also a jewel thief, you were protecting a valuable Tetris block made out of diamond that he stole from you/the museum)

My gem, my gem....I finally have all the gems, I can live rich~ how gorgeous.

You were surprised cause you only left it alone for a few minutes and you got angry a bit at the Rouge for it. You kept calling him Rouge though cause you thought he was not the genderbent version for some reason despite wearing very different clothing.
