-Honeyfern also had a small crush on Lionblaze.
-Goosefeather appeared in Crookedstar's dreams twice.
-Rumours say Brambleclaw knew all along that Lionblaze, Hollyleaf, and Jayfeather weren't his kits and that he acted surprised, but it has never been approved.
-Tigerclaw was thinking about killing Lionheart even when them and Whitestorm were as close as brothers.
-Bluestar believed Runningwind wouldn't have enough patience to have an apprentice.
