It is. That's the good part. I know in my time, a year after the war, he seemed very happy. I don't know a lot about his future... but there's gotta be a lot more good there than there would be here. It's for the best.

[It's just his absence in general, the loss of such a great source of support here in Luceti, that hurts.]
