Outlander: Blood of My Blood is set to introduce a pivotal character from Outlander, leaving fans on tenterhooks after a brief hiatus and only a trailer to keep them going, reports the Daily Record.

The show's official Instagram account shared a post that read: "I know some of you have been waiting for this moment! Henry's brother Quentin aka Uncle Lamb is coming to this week's #BloodOfMyBlood finale."

Accompanying the caption was a picture of Uncle Lamb (portrayed by George Kemp) kneeling on a sandy beach, clutching a shell, indicative of his passion for archaeology and history.

Numerous Outlander enthusiasts took to the comments section beneath the Instagram post to express their views.

One individual commented: "At last! After 7 incredible seasons of Outlander, one more to come with Season 8, and 10 episodes of Blood of My Blood, we'll finally meet the man who shaped Claire - her uncle, Lamb."

Another penned: "Henry's brother? Good casting as he looks similar to Jeremy."

A third remarked: "Of course he's arriving for the finale! Maybe we will get to see our wee Claire too?".

While a fourth fan expressed: "I've been wanting more of a story of his life with young Claire for so many years!"

One viewer remarked: "I hadn't thought about him for ages. But now it occurs to me what if he was a traveller too? That's why he was fascinated with history... Suspicious Claire may be able to travel... brought her up to be the way she is... so she could survive if/ when she travelled. Kind of like Frank taught Brianna a few things like chopping woods, shooting, building fires [sic]."

Another simply exclaimed: "Jesus h Roosevelt Christ it's about damn time! [sic]."

Starz had previously confirmed that the character would make an appearance in the Outlander prequel series, but so far, he has only been mentioned by name.

Uncle Lamb made his appearance in flashbacks during the first season of Outlander and was played by actor Prentis Hancock.

Claire Fraser (Caitríona Balfe) recounted her unusual upbringing and globe-trotting adventures with her archaeologist uncle after she refused to attend boarding school.

Her uncle essentially became her main parental figure after she believed her parents had died in a car accident, and he had a significant impact on Claire.

Furthermore, thanks to Uncle Lamb, Claire met her first husband and historian, Frank Randall (Tobias Menzies).

Unfortunately, Uncle Lamb met a tragic end when he was killed during the Blitz after the auditorium where he was giving a lecture was bombed.

Outlander: Blood of My Blood airs on Fridays on Starz in the USA and on Saturdays on MGM+ via Prime Video in the UK

Outlander season 8 will air on Starz and MGM+ via Prime Video in early 2026
