Fascination
The ministers had been banished and didn't come back, ex-Loser Lord Ozai wasn't feeling helpful, and Iroh's knowledge of the court was several years out of date. When Zuko admitted that he was in urgent need of political information, it didn't take Sokka long to figure out the most likely source of intelligence.
That's how he wound up in Princess Azula's sparse, abandoned bedroom, going through stacks of journals and putting his boots up on the bed.
It turned out she was quite the cataloguer, and had indeed written plenty down- everything from her training schedule to the details of the meetings she attended. Sokka earmarked the stuff that would help Zuko, and then went on to entertain himself with the rest.
He found a journal devoted to him. Aang, Katara, and Toph all shared one, and that writing was fairly dry. But his- it sprawled across pages, and was written in Azula's true voice. She had listed his victories and his capabilities. She speculated on his weaknesses. She wondered why he fought. She complimented his tactics. She bragged about defeating him during the Black Sun. She called his hair stupid.
Sokka had to admit that the attention was flattering.
