Poirot, thanks for posting the episode.
First of all, Percy looks much more dignified than I was picturing. I thought he was a bulky sweater-wearing bookworm type. Now I am really wondering about his background. But, really, vultures are not rare anywhere, any time of year. Silly.
Nick, or I should say the actor who plays him, reminds me of the male character from the former Law and Order show, played by Vincent D'onofrio. He has a lot of similar mannerisms, and speech patterns, and that same feigned ignorance not quite veiling his absolute knowledge about his suspect. I'm trying to decide if I like it from Nick.
Finally, I noticed something about EJ: He calls Sami, Samantha; Abby, he calls Abigail. But Gabi is just Gabi. Interesting.
