At least she can be sure it's not her unique history that makes this difficult. Everybody agrees this is awful.

All right. She is ready has nothing else she can plausibly use as a reason to procrastinate. She can do this. 

She's going to have a heart-to-heart talk with her ex.

To be clear, is this one of those cases where the ex turns out to be a stone-cold crazy killer whose obsession with 'strength' leads her to betray her people over and over again, and help a demon corrupt the children into its servants by making them undergo a cannibalistic ritual?

Yeah, right. She wishes. That would be a best-case scenario, for relationships in the Abyss.

No. Arueshalae was the stone-cold crazy killer who corrupted a pure heart by cannibalistic rituals. Mostly for the fun of it.

And now she has to clean up the mess. Or why else would Desna give her a redemption arc at all?

Oooo-kay. Lann isn't going to touch that with a ten-foot pole.

Fortunately, an archer very rarely needs to. But he'll give Arueshalae some advice, worth its weight in diamond dust, one ranged combatant to another:

Two in the chest, one in each eye; that's how archers say goodbye.

Thanks Lann. That's... really awful, actually. 

But she feels a little better anyway.
