Case-of-the-week: A politician and a woman about pure water were gunned down with only the politician surviving. Turns out the politician and the woman were lovers, but don't feel bad for the wife, she had a mistress too. I wanted to high-five her. Anyway, the politician's right hand woman was the killer because she wanted to be there when he ran for president, but pure water lady didn't think she was worthy of her spot.
I don't know if we knew this before, but Ryan has a sister and her husband was played by David Conrad (Ghost Whisperer).
We also found out Beckett is studying for the Captain Exam. Does this mean bye-bye to Captain Gates? Politics were also thrown into the mix, but maybe Beckett should make Captain before going down that road.
