Quote 1
"I thought I'd scared you off it. How's our haunted mansion faring these days? Still standing?" (4.79)
It's difficult for Jacob to see how Miss Peregrine's decrepit house could have ever been a home, especially when everyone else on the island thinks it's haunted.
Quote 2
"That isn't why you should stay. You belong here, Jacob." (8.298)
Jacob never felt at home in Florida (because he's not ninety years old), so it's not surprising that he wants to stay in a place where he fits in with kids his age… or ninety-year-olds who at least look his age.
Quote 3
"Help us find more people like you. In return, you'll have nothing to fear from Malthus or his kind. You can live at my home. In your free time you'll come with me and see the world, and we'll pay you handsomely." (10.241)
Jacob is tempted by Golan's option, because he doesn't want to have to choose between two other homes—the home where this parents are, and the home where his friends are. But he decides that he can't turn against his new friends merely for the sake of security and power.
Quote 4
"How about when you die? Should I burn all your old manuscripts?" (2.52)
Jacob thinks it's a betrayal of his grandfather's memory if he just throws all his stuff away. But maybe it's just an age difference. What's Grandpa going to do with the stuff anyway, now that he's dead? Dad understands that, but Jacob isn't old enough to get that yet.
Quote 5
"Instead you tried to seduce me with food and fun and girls while keeping all the bad things a secret?" (9.48)
Jacob feels betrayed by Miss Peregrine because she's a little selective with the information she chooses to tell him. Does he have a point? Is she manipulating him?
Quote 6
"I got a .22 in my trunk. You just wait." And he walked off to retrieve it. (1.77)
It's a good thing Jacob has brave friends, too. Well, owning a gun is either "brave" or just kind of a Florida thing. We're not sure which.
Quote 7
"It's amazing, isn't it? Everything he went through." (4.127)
Jacob tries to see the good in Grandpa, though, and tries to understand and admire his accomplishments, like the fact that he survived the war and always lived with honor.
