What if Cloudtail never came to Thunderclan?

i was making an AU for something else, but it included not having cloudtail (it'd take too long to explain so i'll leave it at that lmao). 

what do u think would happen to the series if cloudtail was never brought to thunderclan?

firestar never sees princess, and thus never meets with her and she never gives up her first born to him for his clan.

brightpaw and swiftpaw would still go after the dogs. swiftpaw would still die, but i think without cloudpaw/tail there, brightpaw might have become a medicine cat apprentice. by then, yellowfang died, and cinderpelt is the sole medicine cat. it's not a stretch to think cinderpelt would extend the same kindness and guidance that she received from yellowfang when she herself had been injured and in the medicine cat den for a while. 

since canonically, brightheart helped with medicine cat duties before, her being a medicine cat in the AU where cloudtail doesnt exist makes sense to me.

it's hard to come up with what far in the future events would be changed. dovewing and ivypool would not exist (yay! lol sorry).  and without dovewing, i think the three should have been squirrelflight, leafpool, and emberspark (the OC i made up who is fire and sand's son and leaf and squirrel's brother). 

so this would involve changing brightheart's fate entirely. either swiftpaw survives, and he gets with brightheart, or he dies and brightheart becomes a medicine cat. fire x sand would need to have a third kit to make the three (the prophecy itself would change wording to be your kin and not kin of your kin).

if cloudtail isn't there in TNP, who do u think daisy would have latched onto for comfort and support instead? should it just be spiderleg to get the ball on spider x daisy rolling way earlier?

i cant think of anything else cloudtail has done other than get with brightheart, have whitewing, and then be the grandpa to protags dove and ivy, etc.
