Cecil notes that Ianto seems to be sinking into a state of melancholy, though it was a nice almost-save with that bit about being boxist. Boxist! As if that were a thing. Cecil snorts appreciatively at the joke.

"Well, I'm definitely not a box. Have you had trouble connecting to people here? Who aren't boxes?" He sounds quite sympathetic. "Listen, it's very easy to get sort of...detached. From reality. I mean, the rift already did half the work there for you. That kind of detachment can be dangerous." There's real solicitousness under the PSA-ness. Not to mention a little concern for his own future.
