Squirrelstar, leader of Marshclan, is unsure of how she feels about Flowerheart, but she’s pegged it down as ‘jealousy about how Starclan chose someone from a non-respecting clan to do Starclan Things’.
In reality, it’s a combination of jealousy AND a crush. Her own deputy, Sandspeck, is aware of exactly how Squirrelstar feels due to her own experiences with crushes, and is pretty annoyed at how Squirrelstar doesn’t seem to be attaching the words ‘she’s a really pretty cat and I really want to be close to her’ with having a crush.
