Ethan

Ethan is Autumn's and Kyle's cousin. He first appears in Ratchet Rachel and possibly dies in the same episode.

Season 1
In his debut episode, Rachel attempts to kidnap him. However, he shoots her in the arm and runs off. He bumps into his friend Caden. However, Rachel catches up and shoots Caden in the throat, killing him.

Death (Presumed)
After Stephanie was shot, it's likely that Rachel killed him, as he was of no use to her anymore.
