'Orphan Black' Season 3 Preview, Spoilers: New Trailer Teases Several Changes in Upcoming Third Installment [VIDEO]

'Orphan Black' fans will be excited to learn that BBC America has just released the first teaser trailer for the hit science fiction television series' third season.

As far as the plot for 'Orphan Black' Season 3 is concerned, the latest trailer implies many things. In fact, the 20-second long trailer does not show any characters, but only shows cells dividing endlessly. As the cells multiply, the trailer plays Lesley Gore's "You Don't Own Me" song and finally converts everything into a double helix.

Spoilers reveal that the new video clip makes it clear that the clones have had their DNA strands patented, and that Delphine will be seen fighting Cosima at the Dyad Institute.

At the same time, the multiplying cells in the video could also indicate additional clone projects in 'Orphan Black' Season 3. In fact, viewers will see two clone projects in the upcoming season of the sci-fi show on BBC America and it is very likely that they will clash.

The possibilities are endless, as the dividing cells may also point to new characters which will be introduced in the third season of the series.

Stepping back, 'Orphan Black' Season 2 had a number of cliffhangers in the end, and one of them was Mark being involved with clone project Castor that comprised male clones intended for military purposes. In fact, rumors suggest that new clones of either Mark or his brothers will be shown in the upcoming third season.

In addition to Tatiana Maslany who has been performing amazingly in the role of Sarah, Cosima, Alison, and Helena, even Ari Millen will return in the upcoming season as Prolethean Mark. In fact, Mark is the source of all the male clones. It is rumored that Millen will also said to appear in a crucial role in 'Orphan Black' Season 3. However, it has yet to be confirmed whether or not fans will also see Rachel in the upcoming season, as some rumors claim that she has already been written out of the show.

Currently, 'Orphan Black' Season 3 in the production stage, which is likely to continue until March 2015 and it will premiere sometime soon after that.
