This is quickly just a small chapter of what they all think of you that I completely forgot to put in. This takes place as of before you went on the mission.
Nightmare: Thinks you're very smart, enjoys your company and the nice change to the castle, even if he may never admit it.
Error: Has made a doll of you (of course) and keeps it near him or in a safe place at all times.
Cross: Thinks you're adorable (as do most of them) and definitely already has a crush on you
Horror: Loves Buddy, happy you're so nice and understanding
Killer: Also definitely has crush on you now, would fight Cross to be your number on fan
Dust: Doesn't fully trust you yet, starting to like you
Red: Looks at you with slight pity, but trusts you now
