In a post on fan forum Orwell Boards, he explained that forthcoming episodes would introduce new villains and explore the past of Max Malini (Keith David).
"So far this terrific writing team is surpassing my wildest expectations," wrote Wheeler. "We've broken a number of episodes already and they're all so different."
He continued: "Episode 2 sort of takes the themes of the pilot to a much deeper, richer place and delivers our newest rogue Bluebeard. Episode 3 is a creepy treasure hunt that unearths a number of Palm City secrets. We'll also get a glimpse into the origin of a major upcoming villain, The Lich. In Episode 4 we learn a lot more about Max Malini and the sometimes bloody history of The Cape."
The writer added that he wanted all of the 'powers' featured in the series "to have some basis in reality".
"The general rule of this show is that it's a no-powers, costumed crime-drama," he said.
The Cape - which stars David Lyons and Summer Glau - is expected to air on NBC during the 2010-2011 television season as a midseason replacement.
