So... People die from snake venom being put in some foie gras at a restaurant, and it turns out these people are big in the Internet security world, but then the whole thing turns out to be about someone trying to steal priceless art from Wall Street? I think?
Also, we see Holmes' girlfriend again only to have him break up with her (because she's not as awesome as the criminal mastermind who once held—and broke—his heart). It's as though the writers suddenly remembered they'd given Holmes a girlfriend and said to each other, "We'd better do something with that..." Then looked for a quick way to end that plot point.
Speaking of girlfriends, Holmes pokes Bell in the ribs over his attraction to an assistant district attorney.
On the plus side, no Shinwell in this episode.
I think maybe I'm past being invested in this show. I'll see it through, but only because I'm pretty sure this will be the last season anyway.
