Eric and Pam Don't Kill Sarah
We've been waiting for a gory fate for Sarah Newlin since she's emerged as one of the series's biggest villains (at least in terms of the damage she's caused). She does get what's coming to her, but she doesn't die. First, Eric and Pam let her go, knowing they'll track her down, kill Mr. Gus and the rest of the yakuza, then get her back to synthesize her blood. It's not enough that Eric and Pam become millionaires off "New Blood," but they torture Sarah forever by letting people drink her at $100K per minute. Oh, and she's haunted forever by Steve Newlin, which certainly must suck.
