Cassie: The Witness is here. I thought it was in my head, but...
Cole: What did you see?
Cassie: In the corridor I saw a man in a kind of plague doctor mask. It was him, I know it.
Cassie: It was The Witness. I'm sure of it.
Jones: How do you know for sure?
Cassie: I could feel it.
Deacon: Hold on. The Witness?
Dr. Eckland: He appeared in the form of Aaron Marker, your ex. Are you sure you didn't just imagine...
Cassie: It wasn't a hallucination. He chose to appear as Aaron. And no, I'm not crazy. It happened.
