They've left him alone in his cell.
He can't really be said to be lucid but he has very acute instincts for when there's someone and when he's alone - it's the last of his senses to depart him - and he's alone.
And then suddenly he isn't.
Nod. I don't have a good idea of when I'll be ready to go to your world at all, but if I'm here all winter there'll probably be time for both.
Yes but singing though.
As soon as she has an idea of the tune, she starts singing along in harmony.
I don't mind you taking it at your own pace. Physical health isn't the only important thing here, probably not even the most important one.
She makes a face - 'yeah, but'. There's gradations between 'completely back to normal' and 'just functional'. It's worth aiming for the better ones, if you can. Speaking from experience.
Her nod is only slightly dubious. It's at least a good idea to avoid doing more damage, though, if you can help it, which I'm trying to make sure is the case.
She makes no move to hug him, sends nothing about the actual sensation of being hugged, but sends just the comfort and companionship and sense of being-in-it-together that she'd get from one.
She finishes the blanket, and then goes out to work on the new spell. She comes back in after a few hours.
She sits and waits for a little while. If he's still busy after twenty minutes, she heads down to the pantry and comes back after an hour.
And so she does. She's not trying to interpret his emotional state, but it's automatic enough to be pretty unavoidable regardless.
