Picking up where Tick, Tick, Tick… left off, Beckett’s apartment has been blown away. Castle breaks down the door, frantically calling her name. Amazingly, Beckett is alive! She survived the blast by jumping into her tub. And she happened to be naked. With her towels and bath robes in smolders, Castle covers her body with his coat (don’t worry, he didn’t look) and they escape the fiery ruins.
The team realizes the killer must have remained in Ben Conrad’s apartment when the FBI showed. Beckett finds a false wall in the closet. Inside are the remains of the real killer’s disguise and duct tape residue that indicates Conrad was being held hostage. Beckett gets a call. It’s the killer. He’s disappointed Nikki Heat survived. This was supposed to be over. Now he’ll have to kill again.
Castle points out that the killer must’ve known Ben Conrad to be able to pose as him. After finding out that Conrad was a Knicks fan, Beckett and Castle discover that he made a friend at a local sports bar. The bartender remembers calling the guy a cab one night. Using FBI technology, Agent Shaw zeroes in on possible suspects in the area. One of the matches, Chris Doherty, was murdered six years ago. The killer assumed his identity.
