'Outlander' Season 3 air date, filming update: Is the show diverging from Diana Gabaldon's 'Voyager'?

The casting of David Berry as Lord John Grey, an important character in the "Outlander" series by Diana Gabaldon, has not impressed a section of fans, who believe that the show isn't staying true to its source material.

One of the complaints fans have is that Berry is much younger than his book counterpart, and he looks nothing like that "fine-boned" soldier described in Gabaldon's books. Berry is over six feet tall and has dark hair, but the character he is supposed to essay is just over five and a half feet tall and has attractive blond hair. Because of these differences many feel Berry won't be a convincing Lord John Grey.

Warning: This post contains spoilers from the upcoming season of Starz's "Outlander."

As book readers already know, Lord John Grey will play an important role in Jamie's life in Season 3, which is based on Gabaldon's "Voyager." Grey is the new governor of Ardsmuir Prison, where Jamie is a captive of war, and the British soldier develops a romantic interest in the Scot.

If the show remains true to its source material, then fans can also see a hot moment between Jamie and Grey several years after Jamie is released from prison. This will involve the duo locking lips after Grey refuses Jamie's offer to sleep with him.

Season 3 of the time travel drama is expected to pick up from where the previous season ended, with Jamie rushing to join the Battle of Culloden and Claire, who is in the future, thinking of going back to Jamie.

Meanwhile, the producers of the show have been keeping fans interested by releasing snaps from filming location. Maril Davis, Matthew Roberts, and Jon Gray Steele have all been sharing snaps of mesmerizing Scotland.

"Outlander" Season 3 is expected to air in 2017. An exact air date is yet to be announced.
