The end is coming soon. And it's going to be bloody. HBO will air the final episode of "True Blood" season five on Sunday evening.

Following a season that left virtually none of its characters powerless, or traditionally human, "True Blood" creator Alan Ball warns that the episode has "a big body count," and adds, "Probably more than any episode we've ever had." Will Sam be amongst the casualties or will he be able to shift into something small enough (like a fly) to get away?

"Right, who's the normal person left to react?" said Sam Trammel, the show's Sam Merlotte. "It's all in the [Sookie Stackhouse] books - they divvy out the supernatural creatures as the story goes on. But now even Tara's been turned! The show keeps getting bigger and the writers need something to work with."

Trammel thinks his character has serious trust issues on the show, but sees him eventually outgrowing them. "[Sam] does have trust issues - that irrational fight-or-flee impulse. But I think he's found real love [with Luna], and he's learning how to hold onto it. It's about that moment when you know you want to pursue it in a serious way," Trammel said.

The season finale also marks the end of creator Alan Ball's control of the TV show. "We would prefer that he stayed, for sure. But he's gonna be involved; he's not going to be completely gone," said Trammel. "Alan is that hand on the tiller. He's made a lot of the choices that have made this show a success in the first place."
