That sorta thing is exactly why Sizhui doesn't linger on the idea; he much prefers accepting their timelines coming together and it being the same world. Wen Ning looks like the Ghost General he knows, which is more than enough for him. Best they both avoid the headache of trying to make better sense of it when it's really quite unexplainable.

Too long, he'd imagine the answer being, but since he's only been here for a short time compared to some passengers, he cannot confirm nor deny. Lan Sizhui himself hasn't ever encountered Wen Ning in any form until now and the boy's quite pleased it seems like they're from the same time (or close-ish, at least).

He nods gently while listening, thoughtfully biting his lower lip, teeth sinking deeper once it's affirmed they were together before they'd been whisked away. Control your excitement, you don't know this. But it's fine, he's almost certain his expression is mostly steeled and even if it's not, he can smile after withdrawing his hand and it isn't too odd. “That's the last thing I remembered as well before arriving here on the train.”
