It isn't necessarily the "darkness" that puts firebenders in a disadvantage, but rather the lack of sun (their greatest source) against waterbenders backed by a full moon (their greatest source). For a moon to be full, it has to be opposite of the sun. So when the sun rises, the moon sets, and the tables turn.

22:44 "he has a sister?" - You have seen her already in a flashback: that mean looking girl in the audience when his father burned Zuko's face. 33:02 "it could weaken them too?" - not because of the bending, but in a sense that all life on the planet depends on the moon, like in our real world. If our moon disappears suddenly, life on earth would be in real trouble. ^^ Yes, Sokka has bad luck in the first season. You know who has worse luck? Princess Yue. ^^

Great reaction as per usual!!! And to think season 1 is the “weakest” season.. I can’t wait to see more.
