I think they probably would have and they are not siblings によって the way. Sandstorm's parents were Brindleface and Redtail. Dustpelt's father was Fuzzypelt and his mother was Robinwing.
Probably. Although many prophecies would've never been made... like the Power Of Three. Or... 火災, 火 Alone Can Save our clan.... So.. I'm glad that would've never happened. Jayfeather's my fave character so.., YAY
