They're supposed to give Mac a nemesis this season, which could be great stuff. Some of the most interesting CSI episodes, back when I was still watching in that show, were the ones where Grissom was pitted against his nemesis Paul Milander. Can't wait to see Mac take someone on in the same fashion. But I think he already did meet someone who did a marvelous job as nemesis, and that was Sonny Sassone. I loved the chemistry between Deluise and Sinise. This is NY after all, and there aren't nearly as many mob-oriented stories as one would expect to see, and Sonny and his gang were "new" mob, making it rather intriguing. What does everyone think? Sassone finds yet another loophole to get him out of jail, bringing him back to wreak havoc on Mac's sanity? Or bring in someone totally new? What kind of criminal nemesis would you like to see for Mac? And obviously, any nemesis of Mac's is also a nemesis for the rest of the team and Flack, since they'd all, at one time or another, be working a case against this person, with Mac. Could shape up to be very interesting drama...
