They came with the promise of peace, but there is more to the Visitors agenda. And when ABC's "V" returns this week, viewers will get a glimpse of what these extra-terrestrial friends are really after.

But if you are expecting massive revelations, you'll need to tune in and watch how events unfold because, like Anna, her on-screen counterpart, actress Morena Baccarin is not letting anything slip.

"We're all wearing these shock collars," she joked. "If we say too much, they zap us. But [showrunner] Scott Rosenbaum has promised a lot of great things, like half-alien/half-human babies and interspecies affairs. And who doesn't want to see a lizard bathing or a lizard kissing a human?"

The foundations for human-Visitor relations have already been laid with Fifth Column member Ryan (Morris Chestnut) discovering that his human girlfriend is pregnant with his not-so-human child.

However, one thing that viewers are desperate to know about is the enigmatic Bliss: What it is and how it is controlling the Visitors during their stay on Earth.
