How many envoys were there in Field Colony when Whitebelly died and Blackpelt was demoted? Did any cat try and step in? Or would the numbers not've made a difference considering that Hazelfur and Forrestleaf made the whole incident into a sort of public family drama sort of affair?
When Hazelfur became Captain, his first Second was Russetpelt, Goldenpelt's father. Forestleaf, Moorbug, Dappledmaple, Swifttail, and Screechbuzz were all Envoys at the time.
When Whitebelly died, Russetpelt had only died a few months prior, so Forestleaf became Second. Dappledmaple had retired, Screechbuzz died with his brother Russetpelt, and Swifttail and Moorbug would be the only other Envoys for a while until complications from Moorbug's wounds caused an early death. Goldenpelt would become an Envoy soon after her passing, which is when Swifttail retired, and both he and Forestleaf tried to get Spottedshadow to become an Envoy as well.
So the cats alive at the time on the Council would've mostly been very adamant Hazelfur supporters and would have been grieving alongside with him in their own ways. If they thought Blackpelt's demotion was unfair, they mostly stayed silent.
