I could do without the continued Warrick-and-the-mob stuff. Interesting development with "Humanitarian of the Year" Elizabeth Rodriguez and dogfighting. Sidebar: I liked the woman telling Nick (in Spanish) to take off his shoes, and him replying in Spanish that he was sorry but that wasn't allowed. I don't know/remember enough vocabulary to have gotten the argument between the couple, but that part I did understand.
And at the end we get confirmation that Warrick was right that there's an informant. Gee, didn't CSI: Miami spend like an entire season with a plotline like this?
