Ahmed's house. Holder and Linden invite themselves inside to talk with the very pregnant Mrs. Amber Ahmed -- played by Ashley Johnson, a.k.a. Chrissie from Growing Pains! -- as they "wait" for Bennet to come home. Amber explains that Bennet was "really young," only 23, when she was a senior. Linden says she had a crush on one of her high school teachers, but he was already married at the time. She lies that they used to exchange notes. What a coincidence, that's what Bennet used to do, says Amber. He used to write her long missives, encouraging her to pursue her dreams, wherever they took her. Sound familiar? Linden asks about Amber's whereabouts the weekend before, she says she took the car to visit her sister since Bennet didn't want her taking the bus. Holder, smooth as ever, throws in a complete non sequitur and asks whether Bennet took any movies of Amber when she was a senior. This spooks Amber, so Linden changes the subject, asking if she can use the restroom. She takes the opportunity to explore the house and finds a room full of tarps and cleaning fluid.
Back in the living room, Amber tells Holder she's due next week. She wants a boy, Bennet wants a girl. Holder asks if she ever worries about her husband not coming home at night, what with all the temptation around him. She says she doesn't worry and insists that he was home at 10 o'clock last Friday. When pressed further, though, she admits that Bennet called from his cell phone, not from the land line at home.
Holder is chomping at the bit as they head back to SPD. Linden tells him to hold his horses because circumstantial evidence isn't enough -- they have to put Rosie at the crime scene. Her phone rings, and she tells the lab tech to check Rosie's tissue samples for ammonium hydroxide.
Richmond HQ. He gets a package and a phone call from Jamie. As he opens up the package, Jamie tells him, "I want back in, Darren. It's lonely out here in the cold." After looking at the contents of the envelope, Richmond makes a phone call we don't hear, then he watches as security guards enter, approach Gwen, then head over to another room to pick up his staffer Nathan. Later that night, he tells Gwen he didn't have a choice and had to be discreet. She says she understands. Just then, Councilwoman Yitanes comes in. Richmond calls her out for insinuating Nathan, who also worked for her husband, into his campaign to leak damaging stories to the news. She plays coy, but he knows that she wanted to keep him weak so he'd have to depend on her. They butt heads for a few minutes, but Richmond gets the upper hand this time because Yitanes could get jail time for her felonious actions if Richmond goes to the police with them. Never one to skip a parting shot, Yitanes spills that Richmond had Nathan check out Gwen, too. "Spreading your legs just doesn't buy a girl anything these days," she says and makes her dramatic exit. Gwen is a little peeved.
