Noelle's commentary at the bottom of each page is, as a general rule, hilarious. It ranges from yelling at Nimona's antics, to anticipating the readers' confusion, to observations on how Goldenloin "runs like an idiot".
Goldenloin: HALT, YOU VILLAINS! UNHAND THAT SCIENCE!
Nimona's idea of restraint: Transforming into a cat and jumping from a table to Ballister's head to the top of the fridge with a soda can in her mouth.
While listening to Nimona's tragic backstory, Ballister gets hung up on the witch' problem-solving methods.
Nimona: The spell was slippery. She wasn't a very good witch.
Ballister: Well, I'd guessed that much from her brilliant plan of "get out of the hole by turning the six-year-old into a dragon".
Nimona: Will you please shut up about that?
This becomes even funnier - in a decidedly morbid way - when you read it again with the knowledge that Nimona made that story up. To her, Ballister wasn't just interrupting, he was criticizing her storytelling skills.
On ordering pizza:
Nimona: C'mooon, there's NOTHING edible in your fridge.
Ballister: There are some genetically modified anchovies in the -
Goldenloin's excuse for not telling the Director that the kingdom's most infamous supervillain had hired a shapeshifter: "It's only a little one."
Ballister: IF YOU WERE ANYTHING OTHER THAN A CAT RIGHT NOW.
Even better, a little kid walks into the tent and calls, "Ma! There's a crazy old hobo here talking to a cat!" And Ballister actually tries to explain himself.
A number of the signs at the science fair, which include "ROBOT FIGHT" and "DANGEROUS LASER LIGHT SHOW".
The revelation that knights choose their own names... which means "Sir Ambrosius Goldenloin" picked out that name for himself. There's also a Sir Mansley Girthrod, meaning half of the known knights in the comic deliberately made themselves sound like porn stars.
It's been suggested he meant to name himself "Goldenlion", but someone misspelled it. Whoops.
There's one last funny moment before a long stretch of fairly heartbreaking scenes, and it's a gem. After being caught by the guards, Ballister resorts to screwing with Goldie's head:
Goldenloin: Not so clever after all, are you? You thought you were setting a trap for us, but all along it was a trap for you!
Ballister: Ah well, you got me. Good job.
Goldenloin: ...We DID get you.
Ballister: You did. You've done very well.
Goldenloin: Is this another trap?
Ballister: I just want you to feel proud of yourself!
