I wonder what exactly Hazel sees in Thornclaw in the first place tbh
Is she attracted to old guys who sit and just complain a lot? Which I mean.. fair enough lol, but Thornclaw as a whole just doesn't seem like the kind of cat who returns those feelings a lot. Or at all
It will be funny for him and Mouse to just see each other in the df
Mouse like "Yeah, I am pretty angry, at all these cats. Like Thornclaw who constantly- oh hey, what are you doing here."
The legitimate awsner is that Thorn/Hazel gained popularity yearss ago before Thornclaw became such a massive jerkface and before Hazeltail died and so that is unfortunately the ship I immediately associate Hazeltail with.
The in-story awsner is that Thornclaw and Foxleap are the only single toms in ThunderClan that Hazeltail could be paired with (she's related to Toadstep, Spiderleg is her ex-step dad, and Bumblestripe is too young) and at this point in the fic Thornclaw is a respected senior warrior and a strong fighter and fiercely loyal to ThunderClan, and I've always assumed all of the Frostfur kits are attractive, so. I think a serious lady like Hazeltail would be attracted moreso to him verses somebody younger and carefree like Foxleap.
If I wanted to make Hazeltail happy then I would actually pair her with a she-cat (Icecloud, probably! But also Cinder/Honey/Poppy would work great too!). But I do need her to have her pitiful crush on Thornclaw because. Well. Hopefully I've done a good job of showing that Mousewhisker has a habit of putting cats on pedestals and then struggling when they fall. He really does respect his sister so to see her fall in the same trap as him (pining over a cat who will never return their feelings) really bothers him.
And yeah I'm pretty excited for Mousewhisker to find Thornclaw in the dark forest lol. He's definitely going to have feelings about that!
