Now we find out what Speedle's been up to: matching Carl Galaz's handwriting sample against the employee list and however many other thing were scribbled underneath. Speedle explains how he figured out which sheet of paper had which scrawls: "I measured stroke depth and I isolated the layers. There are seven pages, each dating back week-by-week. We get to the fifth week, he writes a to-do list -- buy gloves, clean gun, disposable cell phone." Horatio muses, "To-do list. Well, he's not the first to do that, but that still doesn't confirm who killed Abby Sandoval, does it?" Speedle replies, "No, so that's why I went back to the second week, and --" He points to a completely different handwriting sample that reads, "BBQ 7A 3D," and continues, "Barbecue. That's not a lunch order…guess whose handwriting that is? I got this [other sample] from public records -- a city lease drafted by Lorenzo Escalante." Horatio's all, "Lorenzo! You're about to lose your lease!" Or gain a new one in cellblock six. It's all in how you look at it. Anyway, Horatio rushes off without bothering to thank Speedle for going to all the trouble to put together the evidence that leads us to conclude that Lorenzo Escalante had no problem engineering the killing of a second innocent person to clear himself of the conviction for killing the first innocent. Given the depths of this guy's depravity, it's a big mystery as to why anybody would think less of Mercedes for distancing herself from this scumbag, as opposed to sticking by her husband the amoral adulterer/conspirator/murderer.

Speaking of someone who stands by her man, Calleigh runs down the hall to tell John Hagen that she's finally stopped working on Horatio's favors to finish his work; she finishes by saying, "This guy is going away." Hagen's all, "You got that right -- patrol picked him up already." Calleigh's confused: "I thought you needed ballistics to file on him?" Hagen clarifies, "We got ballistics -- he shot someone else after we cut him loose." There's a dramatic beat on the soundtrack -- O! Audio manipulation, how transparent thou art! -- and Calleigh's even more confused: "I thought you were going to watch him." Hagen points out that they did, but this guy was Quick Draw McGraw, and plugged a street-level drug dealer before the uniforms could hustle out of the car. Calleigh's overcome with remorse. Hagen's more pragmatic: "One lowlife pops another -- the streets are safer for it. Just be glad it wasn't a taxpayer -- for you and Horatio's sake." I like Hagen. Calleigh covers Horatio's ass by taking all responsibility for that call; it's a noble sentiment, but not entirely accurate, what with Horatio her boss ignoring her workload and putting her on the spot. She may feel morally responsible -- and good for her if she does -- but from a managerial perspective, Big Red's gotta shoulder some of the blame, I think. Anyway, Hagen passes along some career advice with, "I know you look up to the guy. I'm just saying, it's a hell of a lonely road he's walking." Calleigh replies, "Well, that's why I'm walking it with him." Then she breaks into a tremulous chorus of "You'll Never Walk Alone," instantly reducing Hagen to tears and finishing with a group of Chelsea football fans hoisting her on to their shoulders and carrying her off to the nearest pub while Hagen rocks back and forth, wiping his nose on his sleeve. Oh, come on. I just pretend these things happen because it would be more interesting if they did.
