Cridhe was worried about the Doctor. He had been avoiding her recently and she was less than pleased with that. She knew why. All she had to do was look at him and know. She sees that Beverly's door is open, so she enters and sits down. She is nervously playing with her lips as she debates how to have this conversation. It is a few minutes before she can say anything. Without preamble, she begins.

"Say that a passenger might unknowingly pose a threat to themselves or others, what protocols are in place to keep everyone safe?"

Not that she thinks the Doctor would ever hurt anyone. But he thinks he would and that's all that matters right now.
