Amazingly Embarrassing Parents: Or, uncle. When Bruno mistakenly believes that Hiccup has lice, he comments that the kids all had lice once, and that Isabella had it really bad. She blushes while Camilo laughs before telling Bruno what he actually meant.
Comically Missing the Point: Camilo keeps dropping hints to Bruno that Hiccup has a crush on Mirabel, but Bruno doesn't get any of them (when Camilo says Hiccup has the "L" word, Bruno mistakenly believes that he has leprosy, then lice).
Everyone Can See It: While it takes Dolores to reveal to the family that Hiccup likes Mirabel, it just takes a brief interaction with Mirabel for the whole family to know that it was reciprocated.
Oh, Crap!: Dolores' reaction when she discovers that, instead of telling Isabella about Hiccup's crush on Mirabel, she'd told the disguised Camilo.
Shipper on Deck: Dolores struggles to keep the fact that Hiccup has a crush on Mirabel a secret because of how cute it is, a sentiment the rest of the family shares when they find out.
Unwitting Instigator of Doom: Played for Laughs. When Dolores overhears that Hiccup has a crush on Mirabel (since she hears everything), she goes to tell Isabela just to get it off her mind. Unfortunately, she was actually talking to Camilo and the rest of the family was in hearing range, resulting in the rest of the family conspiring to push the two of them together.
