When Monkey Fist agrees to follow "the dark path of the Yono", the Yono symbol appears on the back of his left hand. When he vanishes near the end of the episode, the Yono symbol appears on the back of his right hand.
Sensi uses the same line (this is my way of telling you) that Ron's parents used on him in the TV Movie A Sitch In Time and the episode Big Bother.
In this episode, the running gag this season where someone interrupts Kim and Ron kissing continues on. We finally get to see them kiss, but it was brief due to Hana jumping between them.
In this episode, Ron says to his parents that not saying anything was his way of telling them about Hana's secrets. This is Ron's way to get back at them for using that line on him in the episodes Big Bother and the TV movie A Sitch in Time.
The weapon Monkey Fist continues trying to find in this episode is a continuation from his searches in the episode Big Bother.
Kim: Umm, where's Monkey Fist?
(They notice he has been turned to stone)
Ron: Path of the Yono, path of the Yono.
Ron: (About Monkey Fist)Why is the monkeyman talking about my baby sister?
