Don and Liz arrive and don't see Logan or his car. Liz suggests Logan went home. Come on, Liz! Don't you watch this show? They NEVER go home! Because they are both over the ridge and dead. Liz lifts up Logan's very bloody hand. I'll let it go this time because you're relatively new.
At the site, crime-scene photos of Logan's blood-streaked face are shot. Colby is heard saying, "Single shot, like you saw. Pretty much straight on through and through to the left hand." "Okay, so he saw the gun and probably raised his hands up as a shield," Liz extrapolates. "Yeah, a lot of good that did," Colby notes. You know, to shoot once and kill someone, you either have to be a good shot and know it or just think you're a good shot. I mean, those not that familiar with using a gun as a deadly weapon would seem to fire repeatedly to make sure the target is down and killed. It's usually the pros that get away with a single shot. Unless they're close enough to press the barrel of the gun to the head and be pretty assured of a kill. But that didn't happen here because 1) Logan had room to instinctively throw up a hand between his head and the gun, and 2) there's no scorching on the forehead where the bullet went in. If the barrel had been held to the head, there would've been scorching. Everything I know about murder I learned from Agatha Christie. Colby asks why Liz didn't call him when she got the call from Logan. "Because I was with Don," Liz says reluctantly. And by "with" she means "in the Biblical sense." And by "Biblical sense," she doesn't mean that they were having sex, but that they were arguing like Moses and Zipporah after Moses admitted to taking shrooms before seeing the whole Burning Bush laser show. Basically, the romance has gone out of Don and Liz's affair before we really got to know Liz at all.
ANY-way, Don comes over and says they need to find out where Brett and Josh were that night. Colby reminds them of Mark the Manager's threat. "Wait a second," Liz announces, "Logan lived in Brett's house, right? And that was his legal address and now he's the victim of a homicide?" "So we get a warrant to search his possessions," Colby finishes. "Yeah, that'll get you in the house, right? Good thinkin'," Don says, champing away at his gum. He wasn't chewing gum at Liz's house. Do you think he has a Pavlovian reaction with gum? Like, "Ooh, movement with the case! …Now, why am I craving Hubba Bubba?"
