Wrathion keeps stalling, and it's no sooner that he tries to argue his point that he ends up proving Five's. There's no time for this debate, as evidenced by the battle actively going on around them. It might not be a mirror, but they can discuss the finer points of how they differ when it's safely warded and removed from temptation.

He's not sure how Wrathion cloned himself, but it manages to keep Five from having to fight anyone that may have made him lose sight of the tongue. He braces against the ship as it rocks violently to one side, then twists to glare at the man behind him, only halfway certain he's the real one.

"I needed you to break the door, didn't I?" Five suspects Magnus and Lan Wangji could have done the same, but right now he's the one here. He holds up the box again, practically shouting in his ear. "This held it before. I'd suggest we use it before the ship splits in half."
