Psst! Papa Petrelli Alive?

Nathan and Peter Petrelli survived an explosive flight to outer space at the end of "Heroes," Season 1 -- so who's to say their presumed-dead Pops hasn't been alive and in hiding all this time?

Entertainment Weekly reports that Robert Forster has been cast as the mysterious and maybe-dead Arthur Petrelli. Old Art was sure to have had powers, but it's up in the air as to whether we'll see them in a time travel sequence or present day and in the flesh.

At the show's press tour panel, Cristine Rose, who plays Angela Petrelli, told Entertainment Weekly that there's a big elder Petrelli secret due to be revealed in the season premiere. "There's a secret that comes out that if you're a true fan, you're just going to die. It's a good Angela secret, and it's [not about] her powers."

So ... is it about her hubby? We'd love to fast-forward and find out, Hiro style, but we're just going to have to wait.

Do you think Arthur Petrelli is alive? And is he good or evil?
