Holmes goes back to Terry's office to do some more investigating. Watson says she isn't going to be his apprentice. Holmes answers, "No, of course not. Not in an official capacity. More likely, you'll peddle some fiction to my father about me not being ready to be alone yet. Hmm? Whatever your pride dictates, I shan't hold it against you." Watson again says she's not staying. I like that they've purposely set up a way for Watson to stay and then immediately turned their backs on it. Holmes ignores Watson and pokes at the desk from underneath, looking for secret compartments (and pontificating on the history of secret compartments in cabinetry). He pulls out a drawer and empties it. And then he's distracted by something he pulled out. It's a compact, but it's very heavy. And it's not Terry's shade. Inside the compact, there's a wireless connector dongle. It attaches to the laptop, and suddenly Holmes is looking at the feed from nine hidden cameras. I wonder how heavy that USB antenna is, because I wouldn't expect it to be heavy enough for someone to notice the difference.

Holmes tells Gregson that Terry was collecting blackmail. He enjoys saying "In flagrante delicto" almost as much as Tim Curry in Clue. There are hours of video, but they're not labeled. Gregson moans about how it will take days to have a team of people watching it in shifts. But Holmes happens to be great at watching multiple screens at once! How convenient! So he's just going to stream everything to his ridiculous multiple televisions and stare at them.

Watson comes in with tea. Holmes says she hasn't missed a thing. A lot of this video is prostitute-free, which he finds surprising. Also, Holmes has poured someone's garbage on the floor to see if it causes him to relapse. So far, it has not.

Watson gets a call from Carly Purcell. She says she's fine on the pain-pill front, but she just needed to talk to someone. Hey, we get to see Watson doing her job with someone who wants her to do it! Carly says her mother wasn't what people thought. But her father is sticking his head out the door, so Carly has to go. Well, that was productive. Thanks, Carly!
