Sneak peek video: 'True Blood' preview clips for 'Soul of Fire'

Sunday marks the penultimate episode of the season for "True Blood." Will the season go out with a bang? Or, um, a grenade launch?

Here's three new preview clips for the weekend's new episode, "Soul of Fire" (FYI: There's some NSFW language here)

In the first clip, Sam (in badass mode) and Alcide (in mediator mode) are still on the hunt for Marcus. Maybe they should ask Debbie about that.

In the second clip, Marnie is having some issues dealing with Antonia in her body. It also includes one of the funniest Lafayette lines of the season.

In the third clip, Jason gets involved when Bill, Pam, Eric and Jessica prepare to blow the Moon Goddess Emporium to bits with what appears to be a grenade launcher.

After you watch Sunday's episode, be sure to check back on TV Lust for my episode recap/commentary.
