‘True Blood’: What’s up with the creepy baby?

Vampires, faeries, shifters, werewolves and witches all populate Bon Temps this season on “True Blood.” But the character that’s freaking us out the most? The creepy baby terrorizing momma Arlene (Carrie Preston) and daddy-through-marriage, Terry (Todd Lowe).

Creator Alan Ball admits it’s “great to take a really angelic baby and put scary music” in the scene. Indeed. When speaking to journalists gathered at the Television Critics Press tour on Thursday, Ball explained that the little hellion became a plot point because “once we made the decision in the writers’ room to jump ahead in time, we knew that the baby would be here.”

The child, biological son of Arlene’s dead serial-killer ex Rene (Michael Raymond-James), is now paired up with an even more terrifying tyke — the creepy baby doll.

“I think I actually wrote the script,” Ball says of the introduction of the dirty, mangled plaything to the series last season. “Hoyt (Jim Parrack) and Jessica (Deborah Ann Woll) came together after a season of being apart, and they moved in, and he said, ‘You know, let’s go to New Hampshire. I’ll become a minister and marry you,’ and they hugged. And it just felt like, OK,” Ball reminisces of the almost-too-happy reunion. “So I said, ‘There should be something weird, like maybe let’s just put a creepy doll in.’ So the camera tilts down, and you see a creepy doll. I had no idea where that was going to go,” Ball says. “Then when we came back to work this season, I said, ‘We’ve got to pick up that doll. We’ve got to figure out what’s going on with that doll.’ And, you know, that doll has found its way to the creepy baby.”

Ball won’t spill the certainly evil secrets behind the pair, but confirms “they’re teamed up now. There’s something going on between those two. I can tell you that.”
