Tragically for Xue Yang (and perhaps far less so for Potato), bleeding is definitely not a thing she does.

Ah well!! As it stands, Potato just pouts- quite impressive given she has to keep moving while she does. It's not as if Xue Yang is about to be stopping for a chat in the middle of all this after all. "No way, that's less of the things you're supposed to be cutting then..!!" She's like the civilian target in the shooting gallery, you'll lose 'points' sir, you will!
