I'm kinda ill rn but HEY THAT GIVES ME MORE TIME TO THINK ABOUT MY OCS!!!
Sharkstar has a habit of calling people by nicknames- Lanternglow was "Lan", Starlingstrike is "Stars", etc etc. (He might hate Starclan but the starry sky could be pretty to look at sometimes, so he might as well give Starling a nice nickname! Either that or it's "lil' drowning gremlin" (affectionate) Even Omenstar gets a nickname, but it's more in the "buddy (derogatory)" sense. Omenstar hates it and he finds it funny.
The only cats he doesn't give nicknames too are Myrtle and Alder, because he's afraid they'd take it as an insult and he doesn't want to be forced to pull out and eat his own claws or something. And Whalecall/Dawnfish because he doesn't like them but they're IN STARCLAN SO HE DOESN'T HAVE TO DEAL WITH EM NO MORE-
actually I believe Whalecall/Dawnfish are called LUMPSUCKERS a type of fish so it fits with their names too
