At the beginning of "Risk," Mac comes to the crime scene in a tux, supposedly from a mayoral dinner. A few minutes later, Lindsay turns up in a dress with her hair curled, claiming to have come from the opera. Yeah, right. Can we say torrid affair? They just happen to have the same night off. They just happen to both have fancy events that night. They just happen to show up at the crime scene minutes apart from each other. Suuuurrre. Danny might be too dense to put two and two together, but come on, how obvious was it? I bet they went to a fancy party together. Or maybe ballroom dancing. Or maybe they just wanted to look really nice to go to the movies together. Either way, it looks like something's going on between the head of the NY crime lab and his newest CSI.
