Ezra: "I just want to protect myself and my friends."
Yoda: "And this is why you must be Jedi?"
Ezra: "Yes, and not just them. Everyone. I'll protect everyone. Before I met Kanan, I only ever thought of myself, but Kanan and the rest, they don't think like that. They help people, they give everything away, and I see it. I see how it makes people feel."
Yoda: "Feel. Yes! How?"
Ezra: "Alive. They feel alive, like I do now."
Yoda: "Good. Good. Ahead of you a difficult path there is, Padawan. A Jedi you may yet be."
