Jamie and Murtagh Get Serious About Their Revenge Against the Evil St. Germain in Exclusive Outlander Sneak Peek
05/03/2016 AT 11:00 AM EDT
In an exclusive sneak peek from Saturday's upcoming episode of the hit Starz series, Murtagh (Duncan Lacroix) continues to blame himself for the mysterious brigands' attack on Mary and Claire (Caitriona Balfe) that left him knocked out cold while masked men assaulted the two Englishwomen.
"I failed you," a despondent Murtagh tells Jamie (Sam Heughan). "You put your trust in me, your wife and your child to guard … and that wee English lassie.
"I cannot forgive myself for what happened in that alley," he says.
But the Scottish expats aren't wallowing in their sorrows for too long – Jamie makes it clear that he is convinced that the evil Comte St. Germain (Stanley Weber) is behind not only Claire's attack but her poisoning in last week's episode, and he wants Murtagh's help in seeking his revenge.
"I will lay just vengeance at your feet," Murtagh says. "Or be damned."
Outlander airs Saturdays (9 p.m. ET) on Starz.
