Under the Dome: Pink Stars are going up? what about 2nd season?

Question: With Under the Dome being renewed for a second season, does this mean we won’t discover who or what’s behind the dome? –Glenn
Ausiello: Well, that’s not exactly what the renewal means. Previewing Monday’s season finale, Dean “Big Jim” Norris told Matt Mitovich, “You’re going to learn a lot about the Dome. It’s all very satisfying and it will make you go, ‘Oh, wow. OK, how are they going to play that out in Season 2?’ It sets up for a great second season.” Looking even further down the line, Norris let slip with this teaser for the eventual series finale: “There is a final ending for Under the Dome that is different than the book. And when it was pitched to Stephen King, he said, ‘Wow. I wish I’d thought of that.’”
