Villians: Until the last few minutes, the villian in this episode is percieved to be Monkey Fist, but it is really DNAmy, who is now a gorilla. Her whole plan is to woo Monkey Fist, but he will have nothing of it, so she kidnaps Yori's sensei. That makes Yori ask assistance from Ron. DNAmy thinks Ron is Monkey Fist's arch enemy so he will know where Monkey Fist is. Her plan works perfect.
Kim and Ron:
The arrival of Yori at Middleton High to get Ron's help severely annoys Kim. She gets jealous, but refuses to admit it. She eventually follows them where ever they are going, and eventually catches up with them when they find Monkey Fist.
