Chat Noir finds Marinette and carries her to the balcony at night. When she regains consciousness, they have a little discussion. Here's the conversation they had:
Chat Noir: So, do you have a crush?
Marinette: Actually, there is someone...
Chat Noir: (slightly jealous) And who's the lucky guy?
Marinette: Well... I kinda like Adrien Agreste. (sincerely) He's the kindest person I know. He's always willing to help those in need, even if it means sacrificing something to do so. (dreamily) He's a wonderful person.
Chat Noir: Are you sure?
(thinking to himself- you are jealous of yourself, idiot. Get. Purrofessional. Help.)
