Carrie meets Gregson out in a street somewhere. He tells her she planted that mug. She answers, "I always assumed you knew that." Ha! I was expecting her to indignantly deny it. But no, he thought they were lucky. He says that if Wade Crewes is innocent, he's not going to stay quiet about it, even if it's bad for his career. He ends the scene with, "Fair warning, partner."
Holmes puts on a stupid fake voice as he knocks on Victor's door. Then he picks the lock. It is a crummy hotel room and Watson confirms for us that it stinks. And the floor is sticky. Holmes sniffs around to determine that there's orange juice spilled on the floor. A little more snooping and he's led to the corner of the room, where the carpet has come up from the floor. He pulls it away and finds a loose floorboard. And as he lifts the board, his phone rings. It's Gregson and he needs him right away. It happened again. A triple homicide. Holmes says, "We'll be right there. And Captain, I think I may be able to tell you where the murder weapon is." He pulls a gun out of the floor.
Gregson describes the new case. Two of the victims are the homeowners (with the now-traditional pillows taped to their faces) and one of the victims is a houseguest, who may have surprised the attacker. Gregson says here was a struggle. And there's physical evidence in the form of some cigarette butts from across the street. So the police have a warrant out for Victor and are searching his room right now. I guess Holmes left the gun there, but doesn't it seem like Victor would be able to claim that Holmes planted it? He did pick the lock and pull up the carpet.
Holmes stands where Gregson places the shooter. Gregson tries to talk to him about how he won't hide if Wade is really innocent. But Holmes is concentrating and has no time for Gregson's grand statement of moral culpability. Holmes covers his eye and crouches down. Bell calls to report that they have Victor in custody. Holmes says that'll make it easier to prove he's innocent.
Interrogation chamber. Victor, in Russian accent, says he didn't kill those people. Holmes opens the door and throws an orange at him. It bounces off his right eye. Holmes announces that he's innocent! He's also ticked off now: "Why he hit me?" Seriously, the guy was in prison for twelve years and he just wants to watch some football from Chechnya. And now some weirdo starts throwing oranges at him?
