- Mako: Oh, hey, chief. Did you get my report on the triad murder?
- Lin: Yeah, I looked it over. Nice work.
- Mako: Good. Thanks, mom.
- Lin: ...
- Mako: Why is everyone staring at me?
- Asami: You just called Chief Beifong "mom."
- Mako: What? No, I didn't. I said, "thanks, ma'am."
- Lin: Do you see me as a mother figure, Mako?
- Mako: No. If anything, I see you as a "bother" figure, 'cause you're always bothering me.
- Korra: Hey, show your mother some respect!
How about todomomo getting caught (either by aizawa-sensei or another student) making out? I think this would be hilarious XD
