You can ask him yourself, maybe. I don't really like asking too many questions.

Mr. Yang doesn't show it much, but I sense sadness in his eyes when he talks about his home world.
Wel- I mean, Mr. Yang is actually in his eighties. He might be even older than that, though. He's briefly mentioned alternate timelines and time travel.

Come to think of it, he's actually still pretty mysterious.
[Placing a hand at his shoulder to reassure him.]
Mr. Yang is old. He probably went to bed early because his old man bones hurt. Don't take it personally.

That's weird... He didn't mention he would be going anywhere today. Maybe he's in his room?
