I've got a question when I go through the last several chapters of Season 2. I still feel confused about how the Dai Li turned around beginning to take order from Azula and abandon their own leader, Long Feng. Azula is just a teen, it not very convincing after her stupid short speech, Dai Li began to listen to her.
Dai Li knew the consequence of taking order from Azula instead of Long Feng, the earth kingdom will fall, and beside they get nothing good by joining the fire nation( at least nothing was shown on the show)and let Azula destroy their own element. They can take Azula down easily, but they didn't.
Azula took control of the Dai Li only by intimidation, that's just not convincing for me.
