He finds it fascinating how objects are people are reacting to emotion: that colours can bleed in and out depending on those nearby, that the effect is intensifying. In all his necessities over the coures of the day, he hardly notices what is visible about himself to others, doesn't seem particularly perturbed.

Wei Wuxian lights up objects and people around him in colours, but his own self is increasingly, muzzily grey. Grey and white, like a bleached out ink painting left too long in the sun, with only his eyes staying as intensely dark as they always were.

"Takes on a whole new meaning about colouring someone's world," he says from where he's sitting in the dining carriage, gesturing toward a teapot he's been steeping. "It'd a good thing I'm drinking tea. If it were Emperor's Smile, it'd be too blinding to look at!"

And he laughs, while even his red ribbon tied around the knot of his half-up hair seems the dark of dried, old blood.

His hand darts out to take hold of someone nearby, while his mind's eye is focussed on the improbably shapes formed within the not-void, the deeper void, what the train fears. Wei Wuxian is not a stranger to fear, but he is a stranger to buckling under it in the end, and so he does not.

"Hey, this isn't the end, we'll weather this," he says, and if it's the the Voidtrecker Express or to his companion, there's no outward indication. "You're not alone."

Right in the moments before the connection snaps and they all go flying as the voidtrain spins out of control, the deep vibrations starting up as it sought to flee.
