Reeva is in an akward situation. Right now he was sitting inside the mobile prison getting escorted by the knight's order like before, however, one big difference is that there 2 more people than before.
With Hilda and Leon gone, now he's stuck with Onia. Truthfully he thought he would be alone in here after the knight order and the priest can't find Hilda.
"Why are you still here? I thought you had done your job."
Onia's whole purpose here is to distract the priest, so the fact that she's here means he must have been accused of something.
"...." Onia looked at Reeva "Thanks to someone I have been suspected as a collaborator of the prison break"
"What do you mean? I didn't do anything"
"Still playing dumb, heh? If not you who brainwash Theia then who is it?"
"I didn't brainwash no one."
"Screw you"
