We're in a train station where a well-dressed man with salt and pepper hair -- he very much looks like he should be married to Mary Poppins, but maybe it's just the umbrella -- appears to be waiting for someone getting off the train. When the dude gets off the train, Mr. Mary Poppins follows briskly behind him and then jabs buddy in the leg with the tip of his umbrella. "Excuse me!" says the jabbee, indignantly, and Mr. Mary Poppins quickly apologizes and continues on his way.

And then we see buddy strolling up to his home in Rye, New York -- well, strolling is the wrong word, because he's now limping -- and going in through the front door. Across the street, Mr. Mary Poppins waits.

Inside, the man is now blinking and staggering around his beautiful home, all dark wood fixtures and flooring, lots of windows and natural light. If you're going to collapse after being drugged by a stranger, this is as good a place as any to do it.

When he comes to, he's lying down and covered in spattered blood, restrained on a table, plastic sheeting encircling the table. Behind the sheeting, we can see Mr. Mary Poppins calling medical assistance: "Yeah, he's injured very badly. Please hurry. Cheers." He hangs up and comes in and picks up a syringe lying next to his victim, and gets it ready -- and then very sincerely says, "I'm so sorry, sir. But there's no other way," and then injects his victim in the neck. The man gasps and chokes and starts to convulse, and then stills as he closes his eyes.

Then the paramedics are getting their gear out of the back of the ambulance and apprehensively discussing the fact that they don't have any details about this call, which is "never a good sign" although they're moving a LITTLE slowly for paramedics who are at this point assuming worst-case scenario. Then they see the blood-spattered plastic sheeting and one calls it in as a homicide while the other ventures inside the makeshift operating room. He pulls back the blanket and finds a gaping hole where the man's heart should be. Like most guys, he gets all, "Dude! You have GOT to see this!" with his partner -- and then buddy on the table gasps, opens his eyes, and croaks out "Don't let me die!" much to the EMT's horror.

And then there's Mr. Mary Poppins, back at the train station, carrying the well-known organ-sized cooler, waiting for his train to come in. Credits.

And there's Broyles carrying his coffee into his office in the morning, finding a very chipper Olivia sitting there. "Guess you weren't expecting me back so soon," she chirps, and I think it's more like that Broyles probably hates having people in his office when he's not there.
