Outlander‘s prequel spinoff, Outlander: Blood of My Blood, has easily captured our hearts as it chronicles the intersecting love stories of Jamie (Sam Heughan) and Claire’s (Caitriona Balfe) parents.

While the show may have kicked off with Claire’s parents, Julia (Hermione Corfield) and Henry (Jeremy Irvine) occupying World War I England, the action quickly shifted to the 18th-century Scottish Highlands, as they were whisked away through time at the standing stones of Craigh Na Dun. Their journey may have torn them apart, but it put them in the path of Jamie’s parents, Ellen (Harriet Slater) and Brian (Jamie Roy), just as their forbidden romance was kicking off.

And despite the drama these characters may face in the series, the stars were all laughs as they played a round of Knock Your Blocks Off: Swooon Edition during which they addressed rom-coms, ACOTAR, and much more. As the quartet pulls blocks from our heart-shaped tower, Slater was first up, prompted to share the most romantic TV or movie line she could think of.
