I also made an impulsive decision so here is Fernpaw!!
Name: Fernpaw
Gender: Female, she/her
Age: 9 moons
Personality: She's pretty gentle and honest. Not brutally honest, though. She likes hanging out with kits because the other apprentices make fun of her, and she's already pretty insecure. She is light-hearted, well-mannered, and supportive. She finds Chickadee pretty funny, and likes hanging out with him (even if he insults her because he is probably brutally honest and she can't tell the difference between an abusive friend and a teasing friend). She is silly and easily humiliated.
Relation to Chickadee: I don't think their related through blood, so maybe just a friend/mentor/kitsitter
Interaction Idea: She could be asked by his parents to look after him, and they spend an afternoon together.
