Honestly it doesn't make a whole lot of sense how she does. It would have made a whole lot more sense if it 1. took a LOT more time for her to end up like that and 2. Had her swap bodies/voices a few more times in the process. Her going "Thanks for the new body, it's so young and full of vigor!" to immediately "I'm a giant head!" was... way to fast of a progression?

my guess is she tried to square up against rennala and found out real quick why that was a bad idea
