Gabe Nyland appears in Rose-Colored Glasses. He's a politician and San Diego County D.A. He arrives for the reunion at Rancho Rosa High School a day early. Teresa Lisbon and Patrick Jane go to his hotel to pay him a visit to ask some questions on the double murders of the episode. He’s acting a bit shifty and won’t open his bedroom door for them, so Jane does it for him. Jane reveals that Tess, a current student of Rancho Rosa who is in Nyland's room, is Gabe’s illegitimate daughter, born a few weeks before he graduated from high school. Lisbon remarks that Nyland works with Sacramento's CBI on some cases. He is also a candidate for lieutenant governor in California.
