This is my favorite episode so far.
So many tiny things add up to a series of absolutely fantastic character and lore moments.
Senshi's little senshi-antibodies.
Senshi giving Chilchuck, a father of three, "the talk".
The "pumpkins".
This:
Marcille explaining that the defining difference of forbidden magic is the way it uses spatial magic to open a connection to another dimension from which energy can be tapped, thereby allowing spells to do more than what the mana-pool of the caster would normally allow.
Laios hearing the ghosts of the city during his mana sickness.
Marcille getting petrified mid-sentence.
Laios passing out frothing at the mouth trying to read her spellbook.
"You shouldn't use someone as a fermentation weight."
God this episode is an absolute banger. The list above isn't even comprehensive.
There was this:
And I now realize Goth-Marcy would be mega cute.
