Adagio: “Uh…w-we also have lots of books to, about friendship…and stuff!”
Aria: “Yeah, ehh, accept becoming a Siren and we’ll give you the entire library full…about friendship and stuff.”
Sonata: “Yeah, yeah! We have, like, all sorts of friendly books. Even the cook books! Taco books!”

Twilight: Great! Give me the item you need to seduce everyone. I’ll use it to stop the two of you who still have pendants and save the day anyway! Joke’s on you, suckers!
