Captain Holt: Now, we did a sweep of the room where you and Robert fought.
Philip Davidson: Talked.
Captain Holt: Right, talked. The entire room had been scrubbed.
Philip Davidson: It had been cleaned.
Captain Holt: It had undergone industrial sterilization to remove all traces of blood and DNA.
Philip Davidson: It's a surgical suite. People bleed in there every day. We have to sanitize it by law.
Jake: Ooh, I remembered what I was gonna ask. Did you kill him?
Philip Davidson: No.
Jake: Ah! If you had said yes, I woulda had you!
