Despite an April 19 premiere fast approaching, yesterday saw 'Orphan Black' season 2 offering its first bit of real footage in an exciting confrontation between a vengeful Sarah (Tatiana Maslany) and "Pro-Clone" Rachel, but what about our girl Cosima? Illness looks to be taking its toll in the latest teaser for season 2, but will Cosima fall victim to her own biology?

"This is my biology," claims the microbiology student in her latest round of treatment, from the second 'Orphan Black' season 2 teaser to emerge in recent days. "This is my decision." It looks like Delphine is certainly sticking around as well, aiding in treatment of the same illness that had earlier afflicted German clone Katja, among others. Cosima was as defiant as Sarah, last time we saw, but could our favorite clone really bite the bullet this season? Literally, or figuratively?

So far, we know of ‘Orphan Black’ season 2 that ‘Suits‘ star and fan Patrick J. Adams scored a role in the newest run of episodes, while co-creator Graeme Manson previously said of the new episodes that we'd learn much more about the "Neolution" conspiracy that seems tied to the clones' origins, as well as the mysterious disease the women seem subject too.

More 'Orphan Black' season 2 teasers will be on the way, so check out Cosima's season 2 debut below, and tell us what you want to see from the April 19 premiere in the comments!
