Keltham wakes, to light just beginning to filter in through the bedroom window. He is not used to sleeping through any more light than that, and, what with all the distractions, didn't even close the curtains before falling asleep cuddling a chained-up Carissa.
Oh.
He can sleep on the same surface, and even in the same poorly designed bed, as someone else. Well. He can do that with Carissa; he doesn't particularly like the thought of doing it with anyone else that he currently knows.
It's raining outside, moderately windy. It's not possible to see, underneath the clouds, if the sky is doing anything weird.
Keltham starts to get the - key, how is that a key, he didn't want to interrupt sexytimes to ask Carissa this, last night, but you can literally just look at it and see how it must fit into the lock. Why couldn't you just look at the shape and remember it, and then make another key like that, if you'd trained yourself a bit on fast memorization of what looks like it couldn't be a very large subfeature space? Golarion really doesn't make much sense... well, maybe only sexy keys for bed chains are like this, because the person is chained up and it doesn't matter if they can remember the key's shape.
He's carefully unlocking the keys before it occurs to him to wonder whether he actually wants to Carissa let out; after a few moments, he concludes that he doesn't - want - well, maybe he would, if he thought of things to do - but if he wasn't pushing himself into things -
Keltham realizes he's being dumb; he knows how to think better than this, in familiar domains, knows that the Way there is not to question your ordinary wants so much except on rare special occasions. He felt like letting Carissa out of the chains, so he's going to do that and not trip over questioning the impulse. If he made the wrong decision somehow by acting on that impulse, he'll find out and his brain will update its impulses. Besides, if he wants Carissa back in the chains, he can always put her back in them later.
(A strange wash of warmth at that final thought, unfamiliar, but becoming quickly less so.)
