A couple is seen in bed asleep, under the covers. When they're awakened, we see his bare chest, but she holds the sheet up over her chest.
Sexual references.
Nick and Elizabeth passionately kiss (clothed) in his truck upon being reunited.
Spooner and Sean are partying with two young women. The women are dancing around in their bikini tops.
When Dan says he has something on his Doppler (radar), Stevie jokes that it sounds kinky.
Nick and Elizabeth embracing and making out in the shower. Some are through the frosted shower stall doors where we can see the shape of their bodies together, but no details. Others include close-up views of their mouths kissing, hands running down non-explicit skin and then a head and shoulders shot of them kissing and him nuzzling her neck. We never see any explicit nudity or any actual sex, but the scene is highly sensual.
Elizabeth is in a top that shows cleavage and she's wearing small panties (but not a thong).
Several brief shots of Stevie in her shirt and panties (in bed and standing in the kitchen) where we see a lot of leg and the side of her butt.
