Summary

During the dinner at McAlpine Lodge, Sara and Will observe the other guests while trying to enjoy their honeymoon. Jon, Mercy’s son, drunkenly storms in, screaming at his mother and calling her a bitch. He shoves Will, calls him “Trashcan,” and declares he hates Mercy. After Jon leaves, Mercy cuts her thumb on broken glass. Sara reveals she is a doctor and Will is a GBI agent. While stitching the wound, Sara notices fresh strangulation marks on Mercy’s neck. Mercy admits her ex-husband Dave choked her and that Dave is the source of the nickname “Trashcan.” She confesses she feels unsafe and that nearly everyone on the mountain wants her dead.

Key Events

  • Dinner observations: Sara and Will sit with the McAlpine family and other guests. Sara notices tensions between Drew and Keisha over water spots, and overhears Gordon being called “Paul.”
  • Jon’s outburst: Jon bursts into the dining room, slurring insults, and physically shakes his mother before shoving Will. He uses the derogatory nickname “Trashcan” for Will.
  • Cecil blames Mercy: After Jon leaves, Cecil McAlpine blames Mercy for the incident, and Bitty orders her to clean up the glass.
  • Mercy’s injury: While cleaning broken glass, Mercy cuts her thumb deeply. Sara offers help and takes her to the kitchen bathroom.
  • Sara reveals identity: Sara admits she is a doctor, and Will is a GBI agent, explaining they kept their professions secret.
  • Strangulation marks: Sara examines fresh red marks on Mercy’s neck, indicating recent strangulation. Mercy reveals Dave, her ex-husband, choked her.
  • Stitching the wound: Sara cleans and sutures Mercy’s thumb, providing medical care and advice.
  • Mercy’s final words: Mercy says she feels everyone on the mountain wants to kill her.

Character Development

  • Sara Linton: Demonstrates professional compassion and quick thinking. She sets aside her lie to help Mercy, showing her medical expertise and empathy for abuse victims.
  • Will Trent: Remains calm during Jon’s attack, kneeling to help clean glass despite the insult. His patience and support for Sara are evident.
  • Mercy McAlpine: Revealed as a long-suffering domestic violence survivor. She is isolated within her family, ashamed, and resigned to her situation. Her deep love for the mountain contrasts with her desire to escape.
  • Jon McAlpine: Angry, drunk, and manipulated by his father Dave. His outburst shows deep resentment toward his mother.
  • Cecil McAlpine: Cold and blaming, immediately faulting Mercy after Jon’s tirade. His authority in the family is unquestioned but cruel.
  • Bitty McAlpine: Dismissive and controlling, less sympathetic than her daughter.

Themes, Symbols, or Motifs Actually Evidenced Here

  • Domestic Violence and Control: Mercy’s strangulation marks and her admission of repeatedly taking Dave back illustrate the cycle of abuse. The family’s lack of support reinforces the theme of isolation.
  • Secrecy and Trust: Sara and Will’s hidden identities contrast with the open dysfunction of the McAlpines. Trust is earned only after Mercy reveals her trauma.
  • The Mountain as Sanctuary and Prison: Mercy says the mountain is “in her soul” yet she cannot feel safe there; the same place that represents home is also where she is abused and blamed.
  • Victim Blaming: Cecil immediately blames Mercy for Jon’s behavior, a pattern that enables her abuser and silences her.

Why This Chapter Matters

This chapter deepens the mystery by linking the earlier nickname “Trashcan” to Dave, an absent but powerful off-page figure. It also establishes Mercy as a potential victim or witness: her final line foreshadows that the murder victim may be close to her. Sara’s medical intervention humanizes Mercy and gathers crucial evidence (the strangulation marks) that will likely be relevant to the crime. The chapter shifts the focus from superficial holiday tensions to the hidden violence lurking under the family’s surface.

Study Questions and Answers

1. Why does Jon call Will “Trashcan”? What does this reveal about his relationship with his father?
Jon learned the nickname from his father Dave, Mercy’s ex-husband. This shows that Dave uses petty, malicious tactics to undermine others, and that he has poisoned Jon’s view of Will even though they’ve never met. Jon’s use of the term indicates he is a tool of his father’s cruelty.

2. What medical signs of strangulation does Sara observe on Mercy, and why are they significant?
Sara sees three fresh red marks slashing Mercy’s neck, likely matching fingers, and notes swelling, nausea, and the risk of a broken hyoid bone. These signs are classic indicators of attempted strangulation, a high-risk behavior in domestic violence that often precedes homicide. The injury ties Mercy directly to a violent partner and sets up a potential motive.

3. How does Cecil’s reaction to Jon’s outburst support the theme of victim blaming?
Instead of comforting Mercy or addressing Jon’s behavior, Cecil immediately says, “Look at what you did, Mercy.” This blame shifts responsibility from the abuser (Jon/Dave) to the victim, reflecting the family’s pattern of enabling abuse and isolating Mercy further.
