I tend to agree with the general trend here, that the most likely suspects are Hill, Anna or Emmanuelle.
I think this has more to do with an actor wanting to leave the show, and less to do with the writers/PTB wanting to kill someone off for a ratings boost, which would be temporary at best. But when an actor wants to leave, TPTB often take fullest advantage of it by killing them off, i.e. Rory Cochrane on Miami, Gary Dourdan on Vegas CSI, Sasha Alexander on NCIS, etc. I think someone wants out to pursue other interests, whether it's Anna and her children/home life, Hill and his many other public pursuits, Emmanuelle and her other offers floating in (and I suspect she always meant this to be a temp stint anyway, although I adore her character and would love to see her make a permanent go of it). I honestly don't think this is TPTB "trimming the fat" off the budget by killing off a cast member, I think someone has come to the end of their contract, and has opted not to renew. (Of course I could be very wrong, as sometimes is the case :lol
. Just my Spidey Sense on the subject.
As far as contracts go, the only two that I know for certain have recently signed contracts are Gary and AJ, haven't heard anything about anyone else. So I guess that means everyone but those two are fair game.
Seriously, I do think Hill, EV and Anna are the most likely, but I could also see Carmine wanting out, for some reason, too. And the suspense is killing me!!!
