Some additionally context to explain MJ’s rather inappropriate reaction to a primordial sea beast possessing her younger sibling because I just realized no one else hear’s their voices like I do…
Avery has a very thick Icelandic accent and mostly uses maritime jargon when speaking (Think 17th century “Avast ye matey” classic pirate talk).
And Rahab acts like he just walked out of a Shakespeare play speaking perfect, well articulated old English with an extremely thick Hebrew accent to match.
The three words I use to describe Rahab are Bombastic, Pedantic, and Bravado. Three things Avery is not. So MJ just cannot take this situation seriously AT ALL (If my brother got possessed by a well read spirit I would be more amused than concerned as well tbh)
