Well done. I like how the "analysis" (not quite the word) of Illya's mental/emotional state is not over-sentamentalized, but is nevertheless humanizing and compassionate.

The consideration of his emotional state as a matter of security and safety and ability to do his job, while it on the surface seems almost to trivialize the actual feelings, at the same time emphasizes just how important the feelings are.

And all so simply and subtly done.
