Episode 4 of "Outlander: Blood of My Blood" kicks off with an ominous scene where Julia accidentally spills milk, setting the tone for the ensuing drama. Porter, superstitious by nature, believes they have incurred the wrath of the faeries, prompting Julia to take desperate measures to appease these mystical beings. In a heartfelt letter to Henry, she confesses her nascent belief in such fantastical creatures, hinting at a fragile shift in her reality.
Flashing back to the 20th century, the couple is immersed in joyful anticipation for the arrival of their firstborn. Sharing a mutual admiration for Peter Pan, they lovingly agree to name their son Peter should he arrive. While Henry playfully ponders the possibility of a daughter, he reassures Julia of his unwavering love, regardless of the child's gender.
Present-day, Julia's heart is heavy with fear, haunted by the specter of losing her second child. Lovat, returning home from his travels, looms as a menacing presence. Desperate to avoid his advances, Julia inflicts herself with rashes, hoping to deter him. Meanwhile, the brothel madam, seeking a swift profit, deceives Henry by claiming to have found Julia, sending a brunette prostitute in her stead. Henry, a mixture of distress and relief upon realizing Julia's absence, rejects the prostitute's advances but generously compensates her nonetheless.
Later, Isaac coerces Henry into drafting a letter to Lovat, further entangling them in a web of intrigue. The Grants, lacking concrete evidence, hesitate to discredit Ellen. Yet, Lovat, relentless in his pursuit of malice, is determined to uncover dirt on Ellen, a prospect that fills Brian with dread.
As Lovat prepares to confront Julia, her artificial rashes strike fear into him, prompting him to relent and allow her to visit the apothecary—albeit accompanied by a chaperone. Brian volunteers for the duty, but his supervision remains a constraint, dashing Julia's hopes of escape.
In Leoch, Colum's announcement stirs the air with excitement: they will participate in Beltane, a grand festival scheduled in two months' time. Ellen, assigned to accompany Malcolm as his fiancée, is heartbroken over the impending marriage and pleads with him to call it off, her despair evident in every word.
Colum uncovers a dark secret: Isaac mercilessly eliminates those who disdain his kin, adding to their already dire straits as they are mired in debt, desperately needing funds from Grant. He further proposes that Colum turn Colum into a spy, an idea that incenses her. Her fury also extends to Dougal, who remains oddly submissive, realizing only too late that he is merely biding his time, awaiting Colum's downfall to seize power himself.
Isaac then commands Henry to collect the Quarter Day rents, having hiked the taxes arbitrarily. Henry, devoid of authority to grant any deferrals, embarks on this mission accompanied by Bug, whose presence serves as a deterrent against theft. Violence ensues as the tenants, unable to meet their obligations, react with desperation. One tenant, pushed to his limits, lashes out, only to be brutally subdued by Henry, who experiences a flashback of PTSD, almost致命地 attacking the man until Julia's necklace catches his eye, snapping him out of his trance. Meanwhile, Bug watches with a malicious glee, reveling in Henry's torment.
That evening, haunted by nightmares reminiscent of his 20th-century life, Henry finds solace in a lullaby that Julia once sang to comfort him. Now, amidst his trembling, he sings it himself, while Bug's suspicious demeanor looms.
Elsewhere, Brian and Julia forge a connection, amusement sparking between them as Julia recounts her clever ruse with the fake rashes. Their conversation wanders through topics of family, faith, and literature, culminating in Brian escorting them to Leoch. To Julia's astonishment, Brian asks her to relay a message to Ellen, offering to aid in her escape in return.
Elsewhere still, Henry reflects on a past grievance concerning a national lottery, Julia's explanation that it kindles hope while swiftly amassing funds echoing in his mind. Drawing inspiration, he introduces a lottery system, wherein the winner is exempted from rent for a year. Unintentionally, this creates a loophole where affluent tenants, purchasing multiple tickets, indirectly cover for those struggling to even afford their rent. Bug, irked by this flaw, is reminded by Henry that money is money, regardless of its origin.
Back at Leoch, Julia cunningly exploits Mrs. Fitz's generosity to secure her entrance. With stealthy steps, she slips into Ellen's chamber and reveals Brian's earnest desire to meet her. Ellen is torn between duty and desire, but Julia's persuasive urging drives her to make a choice she knows she won't regret. In a burst of emotion, Ellen inadvertently mentions the possibility of dancing with Malcolm and the fae atop Inverness hill during Beltane. Julia's mind races as she realizes the location is none other than Craigh na Dun, the very place from which her journey through time began.
Together, they manage to slip away undetected and find Brian awaiting them nearby. The couple pours out their hearts, professing their undying love, and Brian vows to assist Ellen in terminating her engagement to Malcolm. Just as they prepare to depart, Julia catches a glimpse of Dougal and hastily flees with Brian. It transpires that Ellen is confined to her quarters, her family fearing she might flee before the wedding.
As they part ways, Julia generously offers to divert Malcolm's attention during Beltane, paving the way for Brian and Ellen's reunion. In return, she seeks Brian's aid in searching for Henry, believing him to be in Inverness. Ellen, too, schemes, abruptly informing Colum that she will not reject the marriage for the sake of the clan. Colum, momentarily suspicious, ultimately chooses to trust her words.
Trouble brews at the Grants' residence as Isaac is dissatisfied with the lottery's outcome. Despite having raised double the required sum, he refuses to hand over the prize. Henry, barely containing his fury, offers to cover the winner's rent as a compromise. Isaac mocks the Highlanders' perception of kindness as a weakness but lets the matter pass this time. After Henry leaves, Bug suggests eliminating him, finding his demeanor odd. Isaac, seemingly concurring, instructs Bug to keep an eye on Henry.
In the 20th century, Henry apologizes to Julia for frightening her with his PTSD-induced outbursts. He declares himself broken and a burden, but she fiercely insists otherwise, reassuring him that she and their child will be his guiding light. He decides to name their daughter Claire, if she should be born a girl, after its meaning of brightness. Presently, he seeks solace in the arms of a brunette prostitute, having nowhere else to turn. He confesses that the woman he seeks is his wife. She offers sympathy and tries to comfort him, but he declines, merely lying down in defeat.
In the climactic scene of Outlander: Blood of My Blood Episode 4, Lovat attempts to bed Julia. She halts him abruptly, announcing her pregnancy with his child. Delighted, he expresses his hope for a son. Porter, who witnesses this exchange, looks troubled by the revelation.
