The second half of a crossover episode with sister show “CSI,” this week’s “CSI: NY” picked up where the action left off on the former, with Mac returning to New York after a whirlwind turn of events in Las Vegas, where he was supposed to meet up with girlfriend Christine for- oh, the horror!- a Celine Dionshow. This only goes to show what getting Dion tickets gets you- in this case, kidnapped. Okay, so there’s a little more to it, but still.
In the front end of “Seth & Apep,” the oddly-titled twofer, Mac went to Christine’s hotel room to meet up for the show, only to find her gone and the room ransacked, with blood trace scattered about the room. Then, her phone shows up at, of all things, the site of a jewelry robbery. Has Christine gone rogue? This would be a left-of-center development, to be sure, but all signs point to yes, which on “CSI” means that all signs are likely wrong.
