Orphan Black Season 2 Scoop: New Clones and Cosima's Illness

Tatiana Maslany better catch up on her sleep. Season 2 of Orphan Black is going to keep her even busier than before.

At the Comic-Con panel for BBC America's cult favorite sci-fi series, co-creator John Fawcett revealed that the clones club is expanding. "I'm not surprised if we unveiled a few more clones in Season 2," he said to the audience's very vocal approval. "I don't think that's letting the cat out of the bag."

Maslany has already played seven different clones, some of which died in Season 1. One of them, evolutionary developmental biology student Cosima, may be next. When last we saw her, she was coughing up blood, a symptom of an illness that could be part of the clones' faulty DNA. Sadly, co-creator Graeme Manson didn't quiet fans' fears. "She has to look at her own science," he said. "I think that's going to be very interesting... It's the health of all her sisters too. I think Cosima is a super-brave character. The truth is it's still up in the air. We don't know what's going to happen to Cosima."

Check out other fun tidbits from the panel:

The clones are real (sort of): The writers based at least two clones on real-life people. Manson's favorite clone, Cosima, is based on the series' science advisor who teaches the History of Science at the University of Minnesota. Intense soccer mom Alison is (loosely) based on Fawcett's sister.

Clone playlists: To get into the proper headspace for each clone, Maslany listens to different music for each. Alison is a showtunes gal; Cosima is into electro, indie, grind and rave; Sarah loves The Clash, Dizzy Rascal and The Prodigy (as does sister Helena, who also throws in some Tom Waits), and Rachel, aka the ProClone, is into '90s slow jamz (yes, with a "z").

Felix the free: In order to land the part of Sarah's brother Felix, Jordan Gavaris reportedly promised he'd be as naked as much as possible for the role. The writers held him to his word, and thus creative costuming including a kimono and a painter's apron (and nothing else!) made their appearances. Gavaris believes Fe's aversion to pants is because they're too "confining."

Emmy surprises and snubs

Revisiting the dead: Clones Beth and Katja got far briefer screentime than the rest, and although the writers would like to do some flashbacks to flesh out their stories, that would ruin the pacing in Season 2. "Maybe Season 3," they said.

Say what? Although Maslany has tackled several different accents already, there are a few that she's not so sure about. "Scottish or Irish would really scare me," said the Canadian actress. But she is really interested in various European and American dialects, including New York and Boston.

Orphan Black begins shooting this fall and will return with its second season in April 2014 on BBC America.
