This is so weird and unsatisfying. Like fine, she injured herself, but literally just taking a step!? With a full cast and everything? And the reasoning is because she's clumsy?
A twisted ankle would've been fine, or tripping over herself and hurting her nose, or any typical injury, not breaking your own leg by trying to move.
The contrast/exaggeration would work right after seeing the move, but waiting 2 days for this feels really weird. And you're deprived the slap stick comedy of seeing the screw up.
