Question: After Laura and Steve leave to go out of town, Nicole calls David to come over. He's in the car with Logan and during this scene, while talking to Nicole, he's rubbing something in his lap, under his arm. What is he rubbing? Is it someone's head or his knee?
Answer: He is petting a dog that's sitting on his lap.
Question: What were David and his friends doing with the dogs? What was their crime?
Answer: Not enough information was revealed in the short scene to make any conclusions and there was no concrete evidence that a (dog-related) crime was being committed. There was not even any indication that a dog was present. One might GUESS that David and his friends prepared dogs for illegal dog-fighting or trained dogs to be dangerous, aggressive watch (or "attack") dogs, but there is no proof. "We're here to see a man about a dog" may sound suspicious or shady, but could mean something as innocent as looking for a lost pet. [00:38:36]. There is a second "clue" much later in the movie when Mr. Walker is talking on the phone: "They're running their own cartel and you can't do a goddamn thing about it"? Mr. Walker probably saw some evidence when he broke into their house. While it might be assumed he means a drug cartel, not all cartels are drug-related. But, relating this scene to the earlier one, it appears "We're here to see a man about a dog" is the code for wanting to buy drugs. (The man who answered the door replied, "Does this look like a kennel?") David and his friends/gang appear to have been selling drugs out of their home. [01:15:55].
Question: What is Steve Walker's occupation?
Chosen answer: He is an architect.
Answer: Why was there a diver in the water at the end? Looking for someone's body?
The tide came in and took David's body away. The divers were trying to retrieve it.
Answer: Of course he is an architect -dontcha know everyone that lives in Seattle is! (according to movies that is).
Answer: I always thought it was a girl giving him a blow job.
Me too! I've seen it more than once and it's not until I'm watching it just now that it shows up as a dog, I could have sworn it was a girl.
