The other thought that Esta did not suppress, because his brain needed something to chew on and seemed to want to pick something that would hurt to bite, is how probably this is all his fault for acting like a Lawful Neutral fool for weeks on end; the moment that he was put into a context strange enough that nothing was forcing him to be Asmodean or rewarding him for being Asmodean.  He probably found it pleasant, and didn't admit it, to be stranded on an alien planet and to not be getting orders every day and new emergencies every three days.  To have so little to do, and not have it be his own fault for doing so little; because what can you do after the spells run out and you can't keep searching for the lost item, after all.  He chose laziness over Evil when given half a chance, and now Asmodeus has abandoned him, and it is all his fault.

(WIS 22 is not enough to stop someone from twisting around their own past story and history in their mind, until it makes events out to be their own fault, and thereby, within their own imaginary control retrospectively.  To have things be your own fault is still to be the big important chooser of your life, and to have the series of past events be a story with a narrative and a moral...

For someone who'd grown up in dath ilan and heard a few proverbs, WIS 22 would be more than enough to enforce the internal choice not to do that.

But without any proverbs at all to hand about what dath ilan would consider real Wisdom, WIS 22 is not enough to invent all the right proverbs starting from Cheliax's baseline.)

When Mariona Merrin comes to ask of him his items, there will be about him a blankness, not an outwardly visible blankness, but delays in response out of a face that has mostly reverted to Chelish expressionlessness.  There is too little reason to do anything; punishment is coming for him, but not in a way where he has any idea of how to evade it, or which actions correspond to more or less pain.

She... wants to borrow his items... and here they are still in this mad Lawful Neutral context that has destroyed his life and also there is not a better way visible to go forward from here, because he has already lost Asmodeus's power.  He wants to change everything and he wants it to have changed in the past and he is aware, in fact, of how all the actions to change things now would not make them better.  Because you do learn quite young, in Cheliax, that desperate lashing-out after you've already earned your punishment, really will not make things better for you.

She wants to borrow his items.

What is he supposed to do with that fact?

There will be a long pause of Esta looking blank before he responds, and the deciding factor that ends up moving him will be the possibility that the Outer God's game is still continuing to some unknown end.

They have no money to pay each other.  There is nothing obvious for him to ask of her to promise by Asmodean compact, in exchange.  He could try saying 'no' and that, too, would not help anything.

But he knows something by now of the way of dath ilan.

"You'll swear to give them back, and you will owe me a favor or trust of corresponding magnitude at some future point," Esta says.  His voice a little flat.

Because in dath ilan you can just ask people to do that, and at that future point they'll just do it fairly.  He's already lost to Asmodeus, and being fucking Abadaran will not make his life visibly any worse, and it grates at him to go on doing this but he cannot think of better things to do.
