Attack of the Clones! A Who's Who of 'Orphan Black' Season 2

There are more.

During the debut season of BBC America's "Orphan Black," Sarah Manning (Tatiana Maslany) discovered she's one of at least 10 clones.

But when Season 2 premieres April 19, Sarah and her "sisters" find that there are others out there. And as she digs deeper into the experiment that produced her and the others, Sarah learns that the conspiracy is bigger — and more dangerous — than she imagined.

The Season 2 trailer is intense, packed with action, and brimming with mysteries. Who is the guy (played by Michiel Huisman of "Nashville," "Game of Thrones") that Sarah is kissing? Where is Kira? Who is the dead clone in the morgue?

Could it be new clone Jennifer Fitzsimmons (Maslany), a teacher and swim coach whose video diaries Cosima happens upon while researching her illness? In Jennifer's video logs, she chronicles her fight against the illness right from the start, after her diagnosis.

So, with Jennifer, that brings the clone total to 11. We have a feeling that number will grow. Let's run down who's who from the "Orphan Black" Season 2 promo photo (from left to right):

Dr. Aldous Leekie (Matt Frewer)- head of the Dyad Institute and a prominent figure in the Neolution movement. He's involved with the clone trial.

Paul Dierdan (Dylan Bruce) - boyfriend and monitor of Beth Childs. He gets involved with Sarah after Beth's suicide — first unknowingly, and then even after learning her true identity.

Rachel Duncan (Maslany) - a "Proclone" who works for the people behind the cloning trial.

Kira (Skyler Wexler) - Sarah's daughter. She's the only known child of a clone, and is kidnapped in the Season 1 finale.

Delphine Cormier (Evelyne Brochu) - Cosima's girlfriend and monitor. She reveals her status as a monitor, despite working for Dr. Leekie.

Cosima Niehaus (Maslany) - a microbiology graduate student who has been examining the genetic material of herself and her fellow clones. Her monitor is girlfriend Delphine. Cosima is suffering from the same respiratory illness as Katja.

Cal (Huisman)- a new character in Season 2 who clearly has a romantic past with Sarah (he's the guy she's making out with in the trailer). Could he be Kira's father?

Sarah Manning (Maslany) - the protagonist of the show. She's a thief who grew up in foster care and learned about the clones after seeing Beth kill herself.

Felix (Jordan Gavaris) - Sarah's foster brother. He is totally loyal to her and befriends Alison.

Alison Hendrix (Maslany) - an uptight suburban mother of two who funds the Clone Club's efforts. Her monitor is her husband, Donnie, though she believed it was her friend Aynsley. Alison signs a contract at the end of Season 1 that frees her from monitoring if she cooperates with the Neolutionists.

Donnie (Kristian Bruun) - Alison's husband and monitor.

Siobhan Sadler (Maria Doyle Kennedy) - Sarah and Felix's foster mother, whom they call Mrs. S. She was Kira's guardian while Sarah was away. She may somehow be linked to the clone trial.

Det. Art Bell (Kevin Hanchard) - Beth's former partner. Sarah works with him while posing as Beth, but Art is starting to put the pieces together about what's really going on.

Johanssen (Peter Outerbridge) - a new character in Season 2. He's described as a "modern-day cowboy" who leads a group of religious fanatics.

And while we may meet even more new clones, aside from Jennifer, we definitely won't be seeing any of the below, as they are all dead (unless "Orphan Black" does some flashbacks):

Beth Childs (Maslany) - a police detective who learns about the clones from Katja. She forms a "Clone Club" with Alison and Cosima to discover more information. She kills herself by jumping in front of a train. Her monitor was her boyfriend, Paul.

Katja Obinger (Maslany) - a German clone who contacts Beth after several European clones are assassinated by Helena. While meeting with Sarah (posing as Beth), she is shot with a sniper rifle by Helena.

Helena (Maslany) - a disturbed, religious fanatic who is brainwashed into assassinating the other clones. She is Sarah's twin, and was raised in a convent. Sarah kills her after Helena murders their birth mother.

Three European clones (Maslany) - all murdered by Helena

"Orphan Black" Season 2 premieres Saturday, April 19 at 9 p.m. on BBC America.
