The "Elementary" episode "You Do It To Yourself" hinted at the perpetrator right in the title. It also hinted at what was happening by the look on the man's face -- a look of acceptance -- right as he was shot through both eyes in the first few seconds of the episode. That was probably a few too many hints for viewers, not knowing what was going to happen at the end, but the ride to get there was entertaining, nonetheless.
There are two concurrent subplots, along with the main plot. Watson's (Lucy Liu) initial rejection of her ex based on his past deeds coincides with the man who had himself killed out of revenge. The other, more subtle subplot had to do with Sherlock's (Jonny Lee Miller) resistance to accept Watson's help when he gets the flu because of long-held conceptions about what will work.
Boredom takes over
Sherlock is incredibly sick but decides to go to a crime scene anyway, because for Sherlock, boredom trumps pain and suffering. Although everyone tells him to go home because he appears to be "dying," as Bell says, Sherlock deduces who the dead man is. The man's shoes, tie, and ratty bracelet spell it all out clearly (at least for Sherlock): He's a professor of East Asian Studies at Garrison University! A quick search on his phone validates the theory, providing them with a name and photo: Professor Trent Anunzio (Richard Topol).
The gambling professor
Once Sherlock, Gregson (Aidan Quinn), and Bell (Jon Michael Hill) locate the Anunzio's office, they find that it seems a bit cramped for someone who is supposed to be a department chair. Sherlock realizes it means the man must be a gambler. Of course! When he spells out the clues, however, it all makes sense: Anunzio had an affinity for the number 13. He chose dank room 13 instead of the larger room 14, his phone number ended in 1313, and he lived in apartment 13. He also smelled like smoke, had white teeth, and wore red underwear. These all pointed to Chinese gambling.
The gambling house
Sherlock convinces the owner (Randall Duk Kim) of the gambling establishment (who initially pretends to be a janitor who can't speak English) to show them the video of the crime from the well-hidden surveillance cameras. It was humorous to see the janitor stand quietly and comply with Sherlock's demands, as Sherlock spouts off all the truths he already knows about the place. From the video, they get a look at the face of the shooter, Ramirez (Lord Jamar).
The real perpetrator
After going down several wrong roads and implicating two innocent people, Sherlock realizes he may have made a horrible mistake. He originally thought it was either Anunzio's T.A., O'Brien (Cameron Scoggins), or Anunzio's wife. Unfortunately, he couldn't take back the fact that the wife was not in the country legally now that her husband was dead, and she had already suffered at his hands. It turned out Anunzio was a real "peach": He tortured and beat his wife, then became furious when she had an affair with O'Brien. He got his just desserts, in a sense, when horrible eye pain revealed that he had inoperable and painful melanomas in both eyes. His revenge was to have himself killed to remove the pain and implicate O'Brien.
Watson initially refuses to help her ex-boyfriend, Liam (Adam Rothenberg), after he lands in jail for allegedly injuring someone with his car while he was blacked-out intoxicated. When Sherlock offers his help, Watson decides to open her eyes and realizes Liam was innocent after all. After Sherlock's assistance works out, Watson decides to share the fact that Liam was the reason she became a sober companion in the first place.
Looking the other way, Watson helps Sherlock with his case, building Sherlock's trust in Watson's abilities. When she notices something almost imperceptible in a photo that Sherlock claims he must have missed because of his illness, it allows them to get to the next step in the case. Watson also gives Sherlock an herbal tea remedy for his flu that turns out to do the job, even though Sherlock initially believed it would have no effect.
