Mathilda： I am already grown up, I just get older.

Mathilda： Is life always this hard, or is it just when you're a kid?
Léon： Always like this.

Mathilda： He's not my father. He's my lover.

Mathilda：Leon, I think I'm kinda falling in love with you.

Mathilda： I don't wanna lose you, Leon.
Léon： You're not going to lose me. You've given me a taste for life. I wanna be happy. Sleep in a bed, have roots. And you'll never be alone again, Mathilda. Please, go now, baby, go. Calm down, go now, go.

Mathilda：I hope you're not lying. Leon. I really hope that deep down inside there's no love in you. Because if there is...just a little bit of love in there for me...I think that in a few minutes you'll regret you never said anything. I love you. Leon.

“This is from Mathilda.”

Léon:Mathilda...Don't you ever do that again or I will break your head...you got that?
Mathilda：Okay.
Léon：I don't work like that. It's not professional...There is rules.
Mathilda：Okay.
Léon：And stop saying"okay"all the time!Okay??!!!
Mathilda：Okay.
Léon：Good...

Léon：It's my best friend. Always happy. No questions.

Léon： Mathilda, I'm glad you don't have a stomachache any more. I don't think it means anything.
