Mathilda: You love your plant, don't you?
Leon: It's my best friend...always happy. No questions. And it's like me, you see. No roots.
Mathilda: If you really love it, you should plant it in the middle of a park so it can have roots.
Mathilda: I'm the one you should be watering if you want me to grow.
Mathilda and Leon have been bonding together over the hitman lessons.
