10.07 - "Sinner Takes All"
Back in a few...
~ Things start off at the Avalon Hotel where a high stakes poker game is taking place. A bunch of high-profile people are participating, including a movie producer, a former rapper turned businessman, and a 17 year old Justin Bieber lookalike. As one of the players wins one of the big pots, windows shatter and robbers make their entrance into the penthouse. One of the players is killed.
~ This isn't the first time the robbers have interrupted a poker game. One of the players had a son killed in one of their previous attacks. The mother, Evelyn, claims to have a genetic disorder that caused her to have two different eye colors. However, Horatio proves that's not the case: she wears a special contact lens that allows her to see special marks on the cards (which is very similar to the CSI episode "Revenge Is Best Served Cold.").
~ Marisol is mentioned towards the end of the episode. Horatio makes a personal connection to Evelyn, as they both have not found closure over the loss of their loved ones.
~ Travers is in this as is Tom. Calleigh and Eric have a few scenes together.
