Jamie and Geneva's sexual encounter is a crucial development in Voyager, the third book in Diana Gabaldon's Outlander series, and this is expected to be featured in Starz's series as well.

Recently, Gabaldon took to her Facebook page to provide more information regarding this sexual encounter after a section of book readers labelled the act as rape. According to Gabaldon, the situation is pretty clear – Geneva is the one who approaches Jamie for sex because she doesn't want to be a virgin when she is married off to a man who is clearly old enough to be her grandfather.

"She's spoiled, impulsive and doesn't care about anyone but herself, so makes up her mind to deprive her elderly husband of the virgin he thinks he's getting," wrote Gabaldon.

In the third book, Geneva flirts openly with Jamie on more than one occasion, and each time he has done nothing to encourage her. But it is a fact that she is sexually attracted to Jamie, and she finds him to be the best candidate to take her virginity.

As to why Jamie finally agrees, Gabaldon pointed out that it was just to protect his family from being hanged.

When Jamie says no to her advances, Geneva "responds by producing a letter that she's intercepted, sent to Jamie by his sister, which not only pinpoints his family and Lallybroch, but contains enough information to get Jamie's entire family arrested—and quite possibly hanged en masse for treason, should the wrong people see it. Which, Geneva tells him, they will, if he doesn't show up in her room at night, ready to do what she requires."

He finally goes to her room and does what she wants.

As Voyager readers know, Geneva gives birth to a healthy boy, William, but dies a few days later. William is then raised by his mother's sister, Isobel, and her husband, Lord John Grey, who develops a romantic interest in Jamie in Season 3 of Outlander.

Outlander will return to Starz in April.
