I've added Hypnos for a very specific reason. Mistletoe's gone off to find if she can find another way to sort out the mess that's happening. Hypnos, being the dragon he is, is going to pretend to be Mistletoe to mess up everything. Not sure past that.
tl/dr: Mistle said 'brb' so Hypnos is going to pretend to be her I know Sky just made guitar dragon but this is idk
