Observe the competition

"I'm not getting my hands dirty, scrubber. I'm just going to watch. I haven't woken up yet." You level with them.

They laugh, and begin training anew. You stand, a little off to the side, and to busy yourself, you remove a sword from the rack, and absent-mindedly grab a whetstone and begin training the blade with it whilst you watch your friends spar.

As you watch, you notice something, out of the corner of your eye.
