#it was actually obi-wan who asks rex to bully cody into wearing the costume

[darthmalewife]

Cody is generally quite a mature guy, but that facade immediately crumbles the minute Rex says, "bet you won't do it" because he will not let him win. It's peak sibling behaviour.

Rex dares Cody to snort lines of salt? No, he'd never. Rex says "I knew you wouldn't." Cody is snorting a line that's as long as he is tall.

Halloween is coming up, and Cody makes a joke about dressing up as a cowboy and getting Obi-Wan to do the same. Rex makes a Brokeback joke. Cody immediately decides he is not doing that anymore. Rex says, "bet you won't do it, coward." Cody turns up in full cowboy gear. Hat, boots, gun holster, and a replica pistol. Hell, he even has a lasso which he uses to irritate Rex.

Rex once dared Cody to burn a marshmallow and then immediately swallow it after pulling it back from the fire, and Ponds has to slap it out of Cody's hand to stop him from doing it.

Wolffe is a bastard and actively encourages Rex to dare him to do stupid shit.

Fox doesn't care. [He does, he finds it so funny.]
