Julie Benz has no illusions about that unbelievable Dexter finale, NBC might be looking to replace Conan O'Brien, and more TV Bites after the jump.

· Julie Benz, who was [SPOILER ALERT!] gruesomely killed off in last week's Dexter season finale, is still trying to convince viewers that her death was not just a horrible dream: "There has been no talk of me coming back to the series in any way. A lot of people have been begging me to tell them that I'm going to come back, and I'm like, 'Rita's dead!' Rita is dead and Trinity killed her... And there has been no talk of Rita being a ghost. No one's approached me about coming back." [E!]
