You joke, but his schedule says "tea time" right now and it hurts to deviate from the schedule. More importantly, "tea time" is his "check up on Ciel in the egg pod time" these days, because when Ciel finally wakes up Sebastian just knows it's going to be in time for tea and he needs to be there to serve it the day the young master needs it.
...Sebastian has many Feelings about tea time. He gives the dial one final, disapproving look before snapping it shut with a small sigh. There's just no helping it with someone who doesn't Understand.]
Most likely, you are correct in that assessment. I suppose there is indeed comfort to draw from that. [Generally speaking, that is - he cares very, very little about "everyone". Trust Snow to consider other people.]
