Bell calls Holmes. He's found the woman. She's at St. Isidore hospital. And now, Holmes and Watson are there, too! And they have the sketch from the sketch artist, which does indeed look exactly like this photo of a woman. Bell has a story about how an "old uni buddy" recognized her. And when he was shown the photo, the neighbor said there was no doubt about it. But here's the thing: she's in a coma! Yes, this woman (Yvette Ellison) tried to kill herself three days ago, and she's been in a coma ever since. Bell sneers at Holmes, "So thanks for the, uh 'consultation.' But I think I'll take it from here."

After Bell leaves, Holmes studies the comatose Yvette, Then he shouts, "YVETTE!" in her face on the grounds that she might be faking. Her deodorant matches the deodorant he smelled on the chair. He looks for something to stab her with. I think that test is going to be less effective when you talk about it in the room with her. Also, I think the show should try to avoid making itself too much like House. Watson tests for pseudo-coma in a more doctorly fashion, which means that she lifts Yvette's hand and lets it fall and hit her in the face. Holmes asks why that's more scientific, and I agree with him. Holmes glances through a book while Watson checks the coma machines and looks at Yvette's chart. Yvette's doctor enters and Holmes tells him that her coma is quite real. Then Holmes and Watson get out of there.

Outside, Holmes tells Watson that the book was inscribed, "To Yvette and Rebecca on your fifth birthday." So Yvette has a twin! And their father was the very rich Charles Ellison, whose charitable trust has been run by Rebecca for years. Holmes got all that from his phone, not by performing marvels of deduction. Because what fun would that be?

At the charitable trust, Holmes barges in and demands to know where Rebecca Ellison is. To his shock and disbelief, she turns out to be a fraternal twin of Yvette's. Not identical at all! She has different hair, eye color, and face shape. So she probably wasn't the person that the neighbor saw. Back to the drawing board!

By "drawing board" I mean the brownstone, I guess, because that's where Holmes and Watson go back to. Holmes is picking locks for practice. And we're using a fisheye lens for no reason whatsoever. He tells Watson that he has concluded that the real killer must resemble Yvette. And must have something against Casey, which makes sense, right? You'd think the murderer probably had some reason to kill that guy. Watson announces that she's found something in a closet. It wasn't Holmes's zipper mask; it was his old violin. She wants him to play, but he explains that the ability to play the violin took up too much space in his brain. Like, remember that time I took that wine-making course and forgot how to drive? The phone rings, and it's Ty, Watson's ex-boyfriend. As she talks to him in the foreground, Holmes is in the blurry background setting fire to the violin. This angers Watson who shouts, "We're supposed to open up to each other. That's how companionship works!"
