[Wuxian believes in all of their abilities to stay safe. Sizhui has been raised well. But this is his son, and he'll always worry and want to protect him.]

He loves you. [It's clear to anyone who sees the two together. And Sizhui is good for Ning.

Wuxian remembers his own concern when he'd first seen the train, but once Wangji had joined him he hadn't been worried. Now he'll make sure he is a very real, very solid presence for Sizhui to lean on. The lack of a laugh, or even smile at his pout has him concerned though...Must increase the absurdity!

He slaps the side of the train with a little grin, as if it's a good little train that does only good.]

It keeps us protected as we travel. Though the rooms are small and narrow. We're all crowded in like we've been planted. [He grins, aiming for the stupidest grin he can manage.] We seem to keep multiplying and the train gets bigger and bigger!

[He shakes his head and waves off the last question.] I wasn't expecting the Void to be so noisy, that's all. Lan Zhan just gets a headache, lucky guy...

[BUT BACKING UP TO WHAT HAPPENS TO THEM.]

We all have to do chores. The two weeks Lan Zhan and I had to wash clothes! [He tilts his head and laughs a little.] We might have done it wrong...
