My favourite thing about all of this is that everyone's flipping the fuck out over angel goddess girl here (Mastemon I'm assuming from the description?) and questioning their beliefs and Dorotea's just like 'haha, nice.'
Though that probably has to do with her absolute lack and even disdain towards her concept of god. If this angel wasn't here to kill her on the spot then as far as she's concerned the angel's either not actually of a higher power or she's a-okay in said higher power's eyes.
That or she's just tired. Probably that.
