Outlander: Blood Of My Blood Cast Go Deep On The Premiere: Ellen's Feistiness, Henry's PTSD, A Game Of Thrones Nod (?) And More — Watch

Can everyone time-travel except us?!

That's how we felt after watching the premiere of Outlander's prequel, Blood of My Blood, which got underway Friday. The spinoff's first two episodes introduced us to Jamie's parents, Ellen and Brian, and Claire's parents, Julia and Henry. By the end of the first hour, via the wonder of time-travel, all four of them exist in the 18th century. (For details on the how and why, make sure to check out the premiere recap, which covers Episodes 1 and 2.)

Ellen is a smart, strategic thinker frustrated by her brothers' desire to use her as a pawn in clan politics. Brian is the bastard son of a local curmudgeon who catches her eye at a gathering, forging an instant connection between them. In the 20th century, Julia and Henry meet during World War I when she intercepts his letter while working in the War Office's censorship department. They eventually get married and have a daughter, Outlander's Claire, but wind up thrown into the past when a fun jaunt to Scotland goes awry.

When series stars Jamie Roy, Hermione Corfield, Jeremy Irvine and Harriet Slater visited TVLine's New York studio, we asked them to go deep on the season's first two installments. Where does Ellen's backbone come from? How will Henry's post-traumatic stress disorder from battle manifest as the season continues? And is it any coincidence that Brian shares a bunch of similarities with a central Game of Thrones character?
