Exploring Five Lingering Mysteries After Watching Danny Boyle’s ’28 Years Later’ Zombie Sequel

The long-awaited sequel 28 Years Later has finally arrived, bringing back Danny Boyle and Alex Garland’s intense zombie horror world. Set nearly three decades after the original 28 Days Later, the film introduces new survivors, evolved infected creatures, and shocking twists.

While the movie answers some questions, it leaves many mysteries unresolved. Fans are now eagerly waiting for the next installment, 28 Years Later: The Bone Temple, set to release in January 2026. Here are the five biggest unanswered questions after watching 28 Years Later.

1. Will Jamie and Spike Ever Reunite?

Jamie, played by Aaron Taylor-Johnson, is devastated after seeing his son Spike leave their safe island colony. Spike, angry after witnessing his father’s affair, takes his sick mother Isla to the mainland in search of a cure.

After Isla’s death, Spike returns briefly to drop off an uninfected baby before leaving again. Jamie finds the baby but misses Spike by minutes. The emotional ending suggests Jamie will go after his son, but will they reunite in the sequel?

2. What Does the Evolution of the Infected Mean?

The movie introduces new types of infected, including “Alphas”—stronger, smarter zombies that show signs of intelligence. Unlike the mindless rage-infected from earlier films, these creatures display strategy and even emotions.

One Alpha, Samson, seems upset when a pregnant infected woman dies. Another infected woman gives birth to a healthy, uninfected baby. This raises huge questions: Can infected reproduce? Are they becoming more human? The sequel may explore this further.

3. Where Did Dr. Kelson Go?

Ralph Fiennes plays Dr. Ian Kelson, a mysterious survivor who has spent years collecting skulls of the dead. He helps Spike and Isla but disappears after sending Spike away with the baby.

Kelson’s backstory remains unclear. How did he survive alone for so long? Will Jamie encounter him while searching for Spike? His fate is one of the biggest mysteries left open.

4. Is Jimmy Crystal a Friend or a Threat?

The movie ends with Jack O’Connell as Sir Jimmy Crystal, a cult leader who rescues Spike from a zombie attack. Jimmy was the boy who survived the outbreak in the film’s opening scene.

Now, he leads a group called the “Jimmies”, all dressed in flashy outfits. His intentions are unclear—is he a savior or a dangerous figure? Director Danny Boyle confirmed Jimmy will be a major character in The Bone Temple.

5. What’s Happening in the Rest of the World?

Unlike earlier films, 28 Years Later reveals that the rage virus was contained to the UK. The rest of the world is seemingly normal, with soldiers patrolling the borders to keep the infected trapped.

But how exactly was the virus stopped in Europe? Are there other outbreaks elsewhere? The movie hints that the infected are evolving—could they eventually break free and spread globally?
