Okay I am putting up almost this entire sequence because it is so fucking cool.
Vriska is dying because Aradia beat the shit out of her, so she possesses Tavros and has him write out messages to himself. Then she makes him take her to her quest bed so that she can die there and enter the god tier.
So I guess Aradia more or less played right into Vriska’s hands, since this benefits Vriska and ends up being a fairly shitty form of revenge.
