Previously on Outlander: In 1946, Claire didn't buy a vase and fell through a time rift, landing in 18th century Scotland. She's married to one dude, Frank, but has just met warrior Jamie. Hope this doesn't cause any horrible, roiling internal conflict!
Claire and the merry band of Scotsmen arrive at Castle Leoch, where Claire is still trying to process her unexpected trip across centuries — and figure out how to get home. Amid playful banter among the group, a jolly older lady greets the returning men. But she stops short upon seeing Claire, who looks muddy and bedraggled and close to naked in her light shift dress. Claire certainly knows how to make a first impression, I'll give her that.
Jamie helpfully introduces Claire to the woman, Mistress Fitzgibbons — Mrs. Fitz, if you're nasty — who ushers Claire inside for some food and more appropriate clothing. Because even when men are fighting and dying and you're under occupation from ruthless British military, the number one threat to peace is still modestly covered breasts.
