...luckily, the shells were filled with rock salt, so it doesn't kill anyone. Bell shows Gregson all the weapons. There's a 9mm pistol, which could have been the one that killed Clark. Bell received a lot of texts from Holmes, most of which suggest that he knows what's going on. Bell answers the phone at "Found McClenahan!" but it's a lie Holmes used to trick him into answering the phone.
Gregson, Watson and Holmes walk in on Mr. Dresden. His wife has some ALS, which means he doesn't want to rush out the door to the secret hotel quite yet. He says he became friends with McClenahan after the Red Team experience. Dresden says that knowing a secret plan to destroy New York did things to them. It made him start going to church again. But it made McClenahan a little weird. According to Dresden, McClenahan thought someone was going to sell their secret, and he used to joke that it might as well be him. Watson thinks that he's killing people to drive up the price. Dresden says McClenahan has a bunker out in New Jersey. But Bell calls to report that he's dead in an alley instead.
When Holmes gets there to investigate the body, he notes that there are aquamarine fibers on McClenahan's body. A blanket covered his face, which is more care than any of the other victims got. To the hotel!
At the hotel. Dresden and his wife are accompanied by a detective. Said detective looks around for hidden assassins and gets whopped over the head by Dresden's pistol. Dresden carefully leaves his hotel room. He sees Vina Mehta and pulls out his gun. Then a policeman in the parking lot shoot at him, so he ducks back into his room. When Holmes gets there, he learns that Dresden has kept the detective as a hostage. He wants the rest of the surviving Red Team. Holmes wants to get in there to negotiate with his secret Holmes Knowledge. Gregson is reluctant, but he lets him in.
Dresden tends to the hostage and his wife. The phone rings and it's Holmes. He would like to be let in. He's unarmed.
Inside, Holmes takes off his scarf. Dresden keeps his pistol pointed at him. Holmes pokes at the minibar, but he can't have alcohol, so there's nothing interesting in there. Holmes says Dresden is clearly not interested in profit. According to Holmes's analysis, he's convinced the plan will get out, and it will result in hundreds of thousands of deaths. Clearly, he wants to kill everyone who knew about it, and he was taking his time to make it look like accidents. But when Holmes meddled, he had to speed up. But why did he wait two years to start? Dresden lowers the gun. He seems convinced that Holmes isn't here to overpower him, so now it's time for his tragic backstory. It was two years ago when his wife woke up and felt a twitching in her hand. Two years later, the ALS has progressed so much that all he can do is try to keep her from getting bedsores. He's been approached by potential buyers for the Red Team Plan. He spent days thinking about it when someone offered to help his wife. He believes everyone's got a weakness like that, and the only safe thing is to kill everyone with knowledge of the plan. And also, he can shoot Holmes, which will show he's serious and still leave him with one hostage. But Holmes says his premise is flawed because other people know about the plan, which was in a memo. Dresden assures him it was labeled "Eyes Only," but Holmes claims to have figured it out long ago. And he told a colleague. The secret's out. It's too late. Dresden considers this and then he points his gun at Holmes and tells him to tell him the plan. Was he bluffing?
