Outlander ‘s penultimate season went out with quite a bang in its final chapter, “A Hundred Thousand Angels,” which saw the Frasers following a collision course toward a mind-blowing family revelation, in which Jamie’s ( Sam Heughan) biological son, William ( Charles Vandervaart) played an integral role.

The Season 7 finale will air just a week later on January 17, and Starz previewed what to expect with this episode description: Denzell must perform a dangerous operation with the skills he’s learned from Claire. William asks for help from an unexpected source in his mission to save Jane.
