You've been too nice to me before. [America's voice trembles, but with how England sounds he's directed all of his enormous willpower at keeping himself together enough to speak.] Whenever I'm nice to you, it's 'cause I wanna be, so you don't have to worry about it or--or anything. I know you're nice. That's--that's what you are, even if you act like a jerk or you shout or you get all proud, you're really--you're nice.
