I Head cannon that they both have slight crushes on each other but they have wives and children so they don’t really realise they do (Or ignore it lol). So when they do this stuff they just think it’s what normal best friends do, it’s not gay to kiss your homie goodnight and tell him that you love him and think of him every moment of everyday ❤️
FireGray but they only realize they're in love after Graystripe has had kits with Silverstream and so they adopt Featherkit and Stormkit and Featherkit becomes Featherpool and Stormkit becomes Stormflight
Firestar: Did you mean what you said, or did you just say it because the world was ending?
Graystripe: ...I really wanna play this cool, but I’m
afraid I’m gonna ruin it if I try to be sexy.
