Shen Qingqiu just got here so I--no y'know what, he's getting de-aged from 15-year-old foxboy to 9-year-old street gremlin.

Tiny Jiu is a feral street child who's a master of crocodile tears, extremely wary of the corrupt adults he makes a living begging from, and particularly unfriendly to any kids he might consider a threat to his livelihood. Luckily there's nothing for him to defend on the train, so he'll be...prickly but sociable? Feed him and gain loyalty points, guaranteed until he ages back up again!
