Outlander‘s final season is making way for more reunions as Episode 4, “Muskets, Liberty, and Sauerkraut,” gears up for a meeting between siblings, Brianna (Sophie Skelton) and William (Charles Vandervaart), the latter of whom is still grappling with his true parentage.

As viewers will recall, in Season 7, William discovered that his biological father was Jamie Fraser (Sam Heughan), dispelling the notion that he was the son of an Earl as he’d been raised to believe by his adoptive father, Lord John Grey (David Berry). The realization sent William spiraling, and Brianna might be able to provide her younger brother with some encouraging and helpful words, now that he’s been clued into their relationship.
