[Really, if Siebren said that he felt bad out loud, he might get a surprise--as in total shock. Xander is unlike Senku, that's true--even if Xander did want payment in turn? He's the trusting sort--Siebren would scratch his back eventually. Doing the same for Siebren first is not important. There's no score being kept in the nephilim's game. Though the question has his brows going up. And staying up.]

Uh. Well. You aren't happy, but that's probably clear. I think. [Most people are a lot to unpack normally, and Siebren isn't any different in that. But wait, there's more. Xander isn't really probing, either, but most people tend to compartmentalize, too, and the good doctor? More so.] Anxious. Depressed a bit, yeah, but that's to be expected. Same with grief. And loneliness. That's there too. [A pause.] A lot of that.

[But he can't condemn the latter feeling either. There's plenty of times where he's surrounded by people on the train--even people he likes--but he's still lonely. It's more for his brother or people who aren't here, like Drake or Rose or Carolyn--but it's loneliness all the same.]
