I kind of wish the evident similarities between hawkfrost and ivypool gets explored now that ivy became a deputy.
Hawkfrost had a close relationship with brambleclaw but there was a hidden jealousy that he was the favorite brother, he was the deputy, the chosen one. When brambleclaw no longer followed hawkfrost blindly he just snapped .
Ivypool was jealous of her sister for being the chosen one, and then dovewing left thunderclan and ivypool saw it as rejection. She chose someone else, she chose another clan. The same way brambleclaw chose thunderclan, dovewing chose shadowclan. Leaving their angry sibling with abandonment issues behind.
Now ivypool is deputy, something hawkfrost never got to truly achieve. I wonder how much of hawkfrost's teaching is left in ivypool, how much of his personality got fused into her own. He was her mentor after all.
I don't think the erins are going to explore it at all. But i think there is so much potential into seeing hawkfrost's apprentice potentially becoming leader of thunderclan. I like to think that even being double dead this guy still haunts the narrative.
