The video of Donny's confession rapidly gains popularity, catapulting him to new heights in his career. However, in a moment of carelessness, he sets an out-of-office message on his email, inadvertently revealing his phone number. This fateful mistake grants Martha unprecedented access to his personal life, as she gains possession of his phone for the very first time.
Armed with this newfound knowledge, Martha calls Donny and threatens to expose his darkest secrets - his rape and sexuality - to his parents. Fearing the worst, Donny rushes to Scotland, determined to preemptively confess everything to his parents. To his surprise, his father confesses that he himself was a victim of sexual abuse, offering Donny a much-needed sense of comfort. Donny spends a week immersed in the warmth of his family's embrace, finding solace in their unwavering support.
Meanwhile, Martha's obsession with Donny reaches feverish heights. She relentlessly calls him, leaving hundreds of voicemail messages. The police advise him to listen to the voicemails and report any threats, but Donny soon finds himself drawn into Martha's twisted world. Over the course of months, listening to her voicemails becomes a compulsive habit, as he once again finds himself pitying her and cataloguing her messages.
However, Martha's threats eventually cross a line when she vows to harm his parents. Donny, now with no other option, reports her to the police. Martha is arrested and sentenced to nine months in prison, followed by five years of probation. Donny never sees her again, but the absence of her constant presence leaves him struggling to adjust.
He shuts himself away at home, consumed by memories of his relationship with Martha. His roommates, concerned for his mental well-being, reach out to Keeley. She, worried about Donny's state, urges him to return to Liz's house. As he moves back in, he stumbles upon the screenplay he had been writing for Darrien. Seeking closure, Donny ventures to Darrien's apartment, but instead of confrontation, he finds himself engaging in polite conversation.
Darrien, who has watched Donny's confession video, offers him a writing job. Donny accepts, but the weight of his past catches up with him as he suffers a panic attack after leaving. Stopping at a nearby pub, he listens to one of Martha's voicemails, in which she explains the origin of her nickname for him - "Baby Reindeer." She reveals that he reminds her of a stuffed animal she clung to during her childhood, the only positive memory she holds from the tumultuous fights between her parents. As Donny listens, tears stream down his face. He orders a drink, only to realize he's forgotten his wallet. The barman, moved by Donny's emotional state, offers him the drink on the house, echoing the kindness Donny once showed to Martha.
