Cas lets out a small sigh of relief before texting Ren
Cas: Hey-are you ok? I was walking back to class and I heard you guys talking...he didn't hurt you, did he?
Cas: It...it didn't sound fine...
Cas: I...ok...
He goes to talk to Aizawa
Cas: Um...sir...I...need to tell you about something...
Cas: ...one of your students had been harassing Ren.
