Biscuit kicks ass as a trainer, at least for these two as they don't seem to mind her training regimen that would leave Spartans and Prussians gasping for breath. It was thus all the more funny when they weren't satisfied with neither losing the number game, and proceeded to solve it with rock-paper-scissors, leaving even Biscuit herself speechless. No wonder Biscuit is enjoying this as well. After all, these two must indeed be like unpolished jewels compared to somebody like Wing. I'm pretty sure Wing would have broken a long time ago if he had faced training this intensive.
