A few long moments passed before he realised that Nineva wasn't going to say anything more. In fact, as he twisted his head to try and see her eyes - but only gently and slowly because he couldn't dare disturb her - it was clear that she had closed them, and with her deeper, more regular breathing, he could deduce why.
Without complaint, Tomen placed his head on her shoulders, not otherwise moving even though her tucked-up-underneath-him position was a little uncomfortable. If she was happier there, then it would do.
They were fine.
