Following last night's intense episode of Heroes, fans are clamoring for insight into future installments.

Fortunately, a pair of stars spoke to E! Online about upcoming developments, and we've got the scoop below!

"The last five episodes are really leading up to a shocking finale," said Jack Coleman. "There's a lot going on."

And Greg Grunberg spilled even more about the conclusion of volume four. According to Parkman's portrayer:

• "Someone is dying at the end of the season, and it's going to be for real. They will not be coming back. And it's not me. That I will tell you."
• "There's a whole fight in a hotel room - huge - with a chair with blood all over it."
• Danko will establish a "concentration camp" for the Heroes. "They built that in the snow, all of those bunkers. It's very creepy and it's very cool. They torch the place."
