Francis suffers from deep-seated trauma because his father used to lock him in the basement as a form of punishment during his childhood.

Francis locks Iris and Lucas in the basement after his paranoia spirals out of control. Having staged a fake zombie attack to maintain control, he then attacks a wounded soldier with a hammer and imprisons his family when they try to escape his increasingly violent and authoritarian rule. The basement mirrors his own childhood trauma, where his father locked him away.

Foreshadowing: Francis's flashback to being locked in the basement as a child foreshadows him repeating this abusive pattern.

Joshua shoots Francis because he mistakes his blood-soaked, disheveled father for a zombie when Francis returns to the checkpoint to recover their van. After Francis escapes his confinement to confront Diego and save his family, he goes alone to the checkpoint, and the horrifying mix of blood and gore leads Joshua to fire in panic, believing he is eliminating a threat.

Foreshadowing: Earlier moments of zombie confusion and Francis's bloodied appearance after battling the reanimated Diego set up this tragic mistake.

• francis killed son
• checkpoint shooting

Francis's breakdown stems from multiple factors: his unresolved childhood trauma from being locked in the basement by his father, his knowledge that Diego is Joshua's biological father and that Iris cheated on him, and his perception that everyone is abandoning him. When he overhears Iris suggest the zombie threat is weakening, his grip on control shatters, leading him to stage fake attacks and ultimately turn violent against his own family.

Foreshadowing: Francis's reluctance to trust Diego's map and his dismissal of Joshua's concerns about the safe zone demonstrate his growing paranoia earlier.

Francis rejects Diego's help and the safe zone because he harbors intense resentment toward his older brother. Diego was always the favored son, and Francis also discovers Diego had an affair with Iris, making Diego the biological father of Joshua. These betrayals, combined with Francis's paranoia, lead him to threaten Diego at gunpoint and refuse any assistance, even when survival options are available.

Foreshadowing: Joshua's earlier insistence on checking the radio for safe zone information and his disagreement with his father's decisions foreshadow his rebellion.

Francis's gun training accidentally attracts a horde of zombies because the gunfire echoes loudly through the area, alerting the undead to their location. Instead of taking Joshua seriously about the safe zone from the radio, Francis prioritizes teaching him to fire a weapon, which proves catastrophic when the noise draws the zombie horde to the mansion.

• gunfire attracts zombies

The wounded soldier confirms that the zombie threat is indeed diminishing, corroborating what Iris overheard about the outbreak weakening. He also reveals he was led to the mansion by Diego, confirming Diego has died.
