The long-awaited season finale of Doctor Who Season 15, "The Reality War," will air on Saturday, May 31, 2025. This marks the end of the eight-episode run of the week-to-week broadcast of the season since April 12, 2025. Viewers will witness the culmination of the season's running arcs as the Doctor battles a reality-warped crisis with central companions.

"Doctor Who Season 15" handed over a complicated story to showrunner Russell T Davies. The finale should provide a climactic resolution to the season.

What happened in the previous episode?

Doctor Who's Episode 7, "Wish World," aired on May 24, 2025, and served as a prelude to the season finale. The Doctor and his buddy Belinda found themselves trapped inside a virtual dystopian world created by an otherworldly entity known as Desiderium, where human wants and desires serve as the energy to stay alive under its influence.

The primary antagonist who takes advantage of this alternate world is a woman named Mrs. Flood. Despite everything that is going on, Ruby Sunday's character is still present, as her troubled past and actions foreshadow additional participation in the season's broader conflict.

The series ending sees the Doctor and Belinda trapped in this parallel world, as Ruby and others prepare for an imminent showdown, which leads directly into The Reality War.


What Happens in Episode 8 of Doctor Who?

The Reality War will conclude the season's central conflicts. The Doctor, Belinda, and Ruby face off against the "Unholy Trinity"—a team consisting of The Rani and Mr. Flood—whose plans threaten the very foundation of reality.

The stakes are high not only in preventing the breakdown of reality but also in saving an innocent life trapped in the middle of the cosmic war. The multiple themes of identity, time, and desire for Season 15, the finale, would be sure to incorporate all these and provide closure on the character arcs.

The official episode run time is about 66 minutes, longer than the regular episodes, suggesting an intricate conclusion.
