Just then, a single drop of liquid falls from the rafters on to Horatio's clothed arm. Naturally, he detects it. So Horatio looks up, notices some sweating plastic bottles, and interrupts Delko's kinky reverie -- this is when Delko picks up the box of porn to get a better look, and we hear a distinctive "click" and the whine of something warming up -- to tell him, "Eric, run."
Horatio hauls ass downstairs, bellowing for everyone to beat feet out of the building. It looks like Delko didn't have the presence of mind to bring the porn with him, since the camera is now giving us a long, lingering look at pictures of a scantily-clad woman in a variety of submissive poses. I love how this show manufactures excuses to pull out the prurient stuff. Anyway, the porn is about to be blown to kingdom come. Everyone sprints all slow-motion style, and then the building conveniently explodes. All the guys high-five on being faster than an extremely toxic and rapidly-reacting meth lab explosion. Well, maybe they do off-camera and away from the blast.
Judging from the credits, the explosion singed Roger Daltrey, because he's doing a little screaming of his own. I'm just curious to see whether Horatio's going to be called on the carpet for blowing up a crime scene; if there's some sort of explosions trend, there should certainly be a correlating disciplinary-hearing trend.
Once we're back from commercials, Speedle's sitting outside the smoking ruins where the barn once was, and Delko's kind of gaping at the damage. Neither one of them comments on how heartily tired they are of having fires break out wherever they go. Horatio comes over to hang out next to Delko and ask if he's okay. Naturally, Delko is. Horatio comments, "This comes under the heading of 'No crime scene is ever safe,' huh?" Delko considers that a lesson learned. Horatio continues, "The problem is that our murder scene has been compromised in a very big way." You think?
