Newt Scamander: Dumbledore, why can't you go?
Albus Dumbledore: I can't move against Grindelwald. It has to be you.
Albus Dumbledore: Do you know why I admire you, Newt? You do not seek power. You simply ask, "Is a thing... right?"
Leta Lestrange: You're too good, Newt. You never met a monster you couldn't love.

Jacob Kowalski: Are you going somewhere?
Newt Scamander: No. We're going somewhere.
Jacob Kowalski: Genius.
Albus Dumbledore: The time's coming, Newt... when you're going to have to pick a side.
Torquil Travers: There's a rumor that Newt Scamander is headed to Paris. I know he's working under your orders. What do you have to say for yourself, Dumbledore?
Albus Dumbledore: If you'd ever had the pleasure to teach him, you'd know Newt is not a great follower of orders.
Albus Dumbledore: Muggles are not lesser. Not disposable.

Gellert Grindelwald: My brothers... my sisters. The clock is ticking faster. My dream, we who live, for truth, for love. The moment has come, to take our rightful place... in the world, where we wizards... are free. Join me... or die.
