-Nutmeg is in the SkyClan's Destiny allegiances, meaning she is most likely still alive.
-Harespring had a crush on Heathertail but he forced himself to end it because he knew Breezepelt already had feelings for her.
-If Finchkit had lived, she would have been a very powerful warrior.
-Darkstripe doesn't believe he deserved to go to the Dark Forest, but after a few moons, he learned to love being there.
-The Erin's were going to make Sharpclaw and Clovertail mates, but at the last second they scratched out the idea.
