Possibly not, because nobody can see around Elizabeth Pena's outsize presence onscreen. I'd love it if she stuck around too -- talk about having antagonists that would make this show more interesting! Anyway, she's here to lay on the political doublespeak for Horatio, thanking him for "all of [his] hard work on behalf of the city. You can't imagine how shocked we all are to learn about Carl." Damn! If she spins any harder, she's going to qualify for Olympic figure-skating. Horatio's not having any of it and says neutrally, "Councilwoman, I'm sure this has been a very difficult period for you." Mercedes is deliberately ignoring his leave-me-alone signal; she adds, "I wanted to thank you as a wife, for clearing my husband. If there's anything I can ever do for you, for your aspirations…" Horatio smacks down the implied quid pro quo by pointing out, "My only aspiration is to find out who killed these women, so don't thank me yet. I'm not done." Mercedes looks appropriately wary as he walks off.
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.
