‘True Blood’ Season 6 Preview: Eric Is No One’s Guinea Pig (Video)

Alexander Skarsgard makes his first "Waiting Sucks" sneak peek appearance

HBO's "True Blood" ventures into a world where Bill (Stephen Moyer) is the ultimate vampire (known as "Billith" to the fandom) and isn't too fond of others.

In a new "Waiting Sucks" behind the scenes clip, Eric (Alexander Skarsgard) learns that there's something (or someone) else hunting down vampires. Who knows what their endgame is, but they want to learn as much as possible about vamp-kind.

"The vampires that they're arresting, they're not taking to jail," a young woman tells Eric. "They're studying y'all, your biology, your psychology, physiology, stuff like that. It's sick."

And, of course, Eric isn't too happy to hear about the facility.

Watch the preview below.

"True Blood" Season 6 debuts Sunday, June 16 at 9/8c on HBO.
