So, I received a bit more than a concussion when I scared Celestia. When I scared her, I might’ve also hissed a couple of changeling curses, such as ‘Kizzzkt’ and ‘kzzrtz’. So logically, since Sunbutt is really smart, probably knows a few changeling words even if she literally cannot vocally reproduce them. Anyways, since I scared and cursed at the Princess while possibly breaching the family friendly tone of the chapter, I think she put a little more power into the spell she hit me with. Because I have a broken rib, or three, a concussion, a cracked headplate, my wings will be broken until I molt shortly after my recovery.
