Ryou ended up making it to class 3 to try and save Fujisawa and likely saw the chainsaw-starving dude trying to kill her/half succeeding and killed him, that's why Yuuya says some stuff about that and we see the panels of him sitting in an interrogation room. According to Yuuya there's not enough evidence to convict him though.
Wait-
Didn’t Ryou get off the Ambulance to go to class 3?
What happened to him??
Wtf was this ending though.
