bristlefrost(paw) before her life goes to shit :(
rereading tbc and she's such a passive character and it's frustrating because she could be used for so much more
in my head, she has a much more active role in the imposter's reign. she truly believes that codebreakers need to suffer to bring starclan back. so she runs the imposter's errands, dutifully, because he's her leader, and clan cats are trained to obey the leader's word.
but her doubts grow as her assignments grow increasingly personal. the breaking point comes when she's ordered to attack her kin, shadowsight (who she would have an actual friendship with). she obeys, and dumps his body in the ravine, but her faith is shaken.
she doesn't find out that bramblestar is a fake until it's revealed to all five clans. like shadowsight, she dedicates herself to making up for her crimes. in the end, she gives her life for shadowsight, i guess, to be true to canon.
