10 Greatest Unspoken Video Game Plot Points

10. The Joker Is Secretly Concerned For Batman During The Clayface Fight - Batman: Arkham City

The Batman: Arkham games are filled to the brim with sneaky Easter eggs and subtle environmental storytelling, though one of the most brilliantly sly occurs during Arkham City's climactic boss battle against Clayface, which The Joker is watching from the rafters.

As discovered by Redditor A_Humble_Knight, if you enter Detective Mode during the battle, you might notice that the Joker's condition is listed as "nervous" while Clayface attacks.

Joker's status calms down, however, when Bats manages to freeze Clayface in place with Freeze Blasts.

This might seem to merely indicate Joker's fear that Batman will fail to retrieve the Titan cure from Clayface, but it's also secretly hinting at the truth of Batman and the Joker's relationship.

Throughout the decades, various iterations of Batman media have suggested that Batman and the Clown Prince of Crime need one another.

And so, by the Joker getting genuinely agitated when Clayface attacks Batman, he's expressing fear that, finally, the Dark Knight might have met his match.

He never outright admits it in the Arkham games, but the Joker wants to do this dance with Batman forever, and his physiological response to the Clayface battle can't hide that fact.
