No worries, I know you don't intentionally ignore posts! (just may take a little while)
Based on something that happened yesterday, was thinking something. MC can learn water magic, but something goes horribly wrong on a spell. Ashley sees this mess up and starts plotting trying to use this mess up as a prank on Metatron, only to realize she doesn't know magic water herself, and pleads with the MC to teach her the exact thing that happened (the mess up, not what the spell is supposed to do) so she can prank Metatron with it. MC looks at Ashley like she's crazy and says "no chance, no way" which only causes Ashley to double down, she wants to prank Metatron in a new and exciting way!
On Ashley's pranks, Metatron seems to accept them as just part of who Ashley is, and doesn't seem TOO upset at the pranks, given how Metatron is gushing about how great Sarah and Ashley are.
