Leafpool broke the warrior code 2 ways.
1) She was a medicine cat, and had kits. Medicine cats are forbidden to have kits or a mate, because they must focus on the Clan, not the kits or their mate. She gave birth to Jayfeather, Hollyleaf, and Lionblaze.
2) She had kits with Crowfeather, whom was from WindClan. That was a problem because Leafpool was from ThunderClan.
Hope this helped! :3
Firestar, Cloudtail, Jayfeather, and Lionblaze.
Leafpool becomes a warrior because she had kits jayfeather lionblaze and hollyleaf
Leafpool becomes a warrior
Leafpool becomes a warrior instead of staying as a medicine cat because she falls in love with Crowfeather, a warrior from another clan, and decides to leave her role as a medicine cat to be with him. This choice goes against the warrior code and the traditional roles within the clan, but Leafpool follows her heart and chooses love over duty. This decision ultimately leads to consequences and challenges for Leafpool and her clan.
Leafpool became a normal warrior in ThunderClan.
No, she does not. She is in love with Crowfeather.
You should listen to your leader and follow the warrior code. But if you believe that you have to break the code then do it like Firestar did when he was an apprentice and a warrior.
No, she just felt betrayed by Squirrelflight and Leafpool for not telling the Clan the truth about who were her real parents. She was angry that Leafpool broke the warrior code and that Squirrelflight pretended to be her mother.
Because Hollyleaf loved the warrior code, and when she found out that her birth was against the code she went crazy. And Hollylead never exiled her mother, Leafpool was never exiled from ThunderClan.
No, at least, not yet. Leafpool became a warrior after Hollyleaf told the others of her secret.
Leafpool broke the warrior code by mating with Crowfeather. Apparently she did not want to tell anyone, nor risk her posistion as medicine cat, hence why she left the camp with her sister when the three were coming. They lied and said Squirrelflight had the kits, when they returned. Since no cat saw Leafpool give birth, they could not really contradict.
Leafpool died due to a collapsed lung in "The Last Hope" book in the Warrior Cats series.
