* Longtail's death in ''Fading Echoes''. Briarlight being crippled, too.
* Anything related to Graystripe that isn't Firestar. His first mate dies, his second mate gets horrifically ill, his children die (Feathertail), run away (Stormfur), get crippled (Briarlight), perform {{Face Heel Turn}}s (Blossomfall) or get rejected a mate of their own (Bumblestripe). He himself not only goes through this, but gets kidnapped and returns to find everyone migrated away and his old home destroyed.
* That last line in ''Sign of the Moon'', "I will wait for you forever, Jay's Wing!"
* Firestar's death at the very end of ''The Last Hope''.
