They dropped a lot of "When you're better, things will be different..." lines this episode, so I imagine it'll happen at some point.
But...with the amount Rodrik should have been injured by a horse crushing him, it's remarkable he's as well as he is even now. :S
Imagine if he pulled off a surprise.
Like, he's got his crutch, the Whitehills laugh at him, the camera is under him facing the Whitehills, then a close up on the Whitehills and they're HORRIFIED.
Camera goes to a shot of the whole of Rodrik. He's standing tall, Sword in one hand, crutch in the other. And he drops the crutch, staring right at them with a grin. Drogo style.
Random Whitehill- "Oh *expletive*"
You know what happens next. Teaches Asher how its done. hahaha
