The cast of Showtime's Penny Dreadful arrived in San Diego for Comic Con this week for a panel Thursday night, giving insight as to what fans can expect for the drama's second season.

'Penny Dreadful' Season 2 Q & A

Before heading into the ballroom, however, Josh Hartnett (Ethan Chandler), Reeve Carney (Dorian Gray), and Harry Treadaway (Victor Frankenstein) sat down to chat with HitFix's Greg Ellwood in a more private setting (featured below). The actors discussed what initially drew them to the series and revealed that they're relatively in the dark about what's coming next.

"Wes' re supposed to get the scripts next week," explained Hartnett, who added that the delay was probably intentional to avoid the actors entering Comic Con with any spoilers.

"I feel like when you don't know exactly where you're going it can be an advantage," admitted Treadaway.

Carney agreed, adding that creator John Logan keeps them "in the dark a bit," which is helpfully in developing their characters.

While the actor's claimed to not know much about Season 2, Ellwood couldn't help but ask some of the big questions, such as what exactly Ethan is and whether or not fans will ever get a glimpse at the infamous Dorian Gray portrait.

Hartnett discussed his portrayal of the mysterious Ethan, noting that he liked the idea of "multiple layers of hiding" so much so that he pushed for the character to wear a fake mustache over his mustache for his opening scene in which he gives a sharpshooting performance.

The speculation that Ethan would be revealed as a straightforward werewolf was disrupted when he miraculously performed an impromptu exorcism on Vanessa Ives (Eva Green). Hartnett agreed that there is definitely something going on. "We've have a lot of discussions about where Ethan is gonna go," he explained, "But we don't know what he'll end up being eventually."

As for the Dorian Gray portrait, Carney wasn't able to give too much away. "Most of the time I was imagining what I believed to be the accurate manifestation of whatever would be on that painting…" he said, "but they did have a version of it that I saw at one point and we did shoot it… I'm not sure if they'll potentially save it for later or maybe we'll re-shoot it with a different version of the painting."

The actors all insisted that they wish they knew more, but for now the only thing they could confirm with any certainty is that production for the second season will begin in September.

As for what the future holds, Hartnett joked that it never looks good. "There's no good ending in TV," he laughed, "You either get canceled or you get killed off."
