Thanatos still wears his red hoodie and other train-issued clothing. However, he's floating above the ground and seemingly lost in thought until someone calls out to him.

"You've been captured by the train to help worlds other than your own." While others might paint the whole ordeal in a more favorable light, Thanatos still cannot help but consider this being captured. His circumstances differ wildly from others. "But I would ask someone else. I was only trapped a platform before this one."

And he's been in some level of mental and emotional (Why does he have these?!) distress for 16 days straight. Thanatos is really not the best passenger to get an introduction from.
