Betrayal Quotes in Miss Peregrine's Home for Peculiar Children

How we cite our quotes: (Chapter.Paragraph)

Quote #1

I thought about it, looking at the pictures and then at my grandfather, his face so earnest and open. What reason would he have to lie? (Prologue.38)

At this point, Jacob does believe Grandpa—which is great because Grandpa isn't lying to him. But when kids make fun of Jacob at school for believing these stories, Jacob changes his mind. It's not Grandpa who betrays Jacob at all, but the other way around.

Quote #2

I told [Grandpa] that a made-up story and a fairy tale were the same thing, and that fairy tales were for pants-wetting babies, and that I knew his photos and stories were fakes. I expected him to get mad or put up a fight, but instead he just said, "Okay." (Prologue.45)

Or maybe Grandpa does betray Jacob here. Why doesn't he try harder to convince him?

Quote #3

My dad explained it to me: Grandpa had told him some of the same stories when he was a kid, and they weren't lies, exactly, but exaggerated version of the truth. (Prologue. 46)

Maybe Grandpa was upset because his own son kind of betrayed him years ago by losing trust in him.
