Book/Relationships/Coiny

In Reveal Novum, Book's definition of Coiny says: "Coiny - likes to slap Firey. But what I don't get is how you slap fire. Won't your hand just go right through? Whatever." In Get Digging, Book stops Coiny from taking Teardrop to WOAH Bunch, saying that Teardrop will only switch if she wants to switch. When Coiny gets her to switch anyway, Book complains to Fries that she can't believe they just did that.

In No More Snow!, Book informs Coiny that the HPRC got crushed. In It's a Monster, Book helps Coiny understand the implications of the HPHPRCC's self-destruction.

In Welcome Back, Book lifts Coiny during her explanation of recommending characters. However, this may not be canon.
