Question: Please tell me Sam (Vanessa Marcil) isn't the one dying on Las Vegas.

Answer: All I'll say is that the decision to kill off this particular character came after much internal discussion between the network, studio and the show itself. The only folks not consulted were the cast. "They thought it was a joke," says Thompson. "They read the script and went, 'What?'" Oh, and one other thing: The two-part episode marks the departure of another actor on the show. "Someone else," Thompson says, "will never step foot in the Montecito again."
