While i'm worried they will use Chi travelling alone as another opportunity to make even more awfull stuff happen to her (pls dont) it's pretty in character after all, she is that kind of stubborn while also probably being emotionaly exausted by the whole ordeal, there has to be some guilty for making Yu "waste" time taking care of her. Just hopping here she just comes back to school safe and sound, PLEASE.
BUT cmom what hospital gonna let a MINOR get discharged and leave the hospital ALONE, after a traumatic incident and a huge crime?! Not even a call to the school, police or the friend that stayed the whooole time? I guess they must have tryed to call the mom at least, but did not one of the nurses try some lies like "Just a last last madication(placebo) before you go" or exan to keep her a little longer until they got someone there? It's what we at least try in the hospitals i worked...
Thanks for the translations!
