One of the many mysteries surrounding The Amazing Spider-Man 2 is who Felicity Jones is playing. The actress hinted last month that she is playing Felicia Hardy, a.k.a. The Black Cat. She confirmed that she is playing a villain just a few days later.

Felicity Jones has now revealed another intriguing piece of information, which still leaves her identity as Black Cat a mystery...But at least now we know whom she is playing.

"It's all quite shrouded in secrecy, but I'm the Goblin's girlfriend - I'm in a relationship with him, and his accomplice. I'm on the dark side."

When asked her character's name, she stayed tight-lipped.

"I can't say actually. It's all in the vaults of Marvel. I love all that secrecy, I think it's great. It builds anticipation, there's too much transparency in everything these days."

Major Spoiler! Proceed with caution.

Dane DeHaan plays Harry Osborn, who is confirmed (we've seen this part of the screenplay) to be turning into the Green Goblin at the end of The Amazing Spider-Man 2. Some have speculated that The Amazing Spider-Man 2 will lead into a Sinister Six storyline, which includes villains such as Electro, Doctor Octopus, Kraven the Hunter, Mysterio, Vulture, and Sandman.

In the history of the comic books, Black Cat and Harry Osborn are never boyfriend and girlfriend. Neither Black Cat nor Felicia Hardy have a relationship with Green Goblin. Peter Parker, on the other hand, has a long standing relationship with Felicia, as they are an on-again, off-again romantic pair, with Hardy sometimes drifting into villain territory. It's quite possibly though, that this version of the Spider-Man legend will change that. They are completely changing Green Goblin's history, with Norman Osborn never becoming the villain himself. So Black Cat and Green Goblin could be boyfriend and girlfriend.

The actress also spoke her about experience on the set, and how this was like nothing she had ever done before.

"Spider-Man is completely different from anything I've experienced before, and a real departure from what I've done before, which I've really enjoyed doing; something on a completely different scale, and with it being a cartoon, it was really good fun actually. It was really fascinating to see how a film is made in that way, which is so foreign to what I've done before."
