'Doctor X' Hits 18.5%; a Creator's Episode Breakdown Trends Too

First people watch the story. Then they watch someone talk about the story.

In the October 17 fourth episode, Gye Su-jeong (Kim Ji-won) clashed with new surgeon Na Dae-il (Jang Seung-jo) over a patient's treatment. Reports citing Nielsen Korea gave the episode an 18.5% national average and a 20.8% minute peak. Gomong uploaded an independent review of episodes three and four the next day; the creator's interpretation is not an official SBS statement.

The 18.5% figure is the nationwide episode average; 20.8% is its minute peak. They are not interchangeable. Interest in an independent recap is a different phenomenon, offering a way to revisit the characters' conflict and possible next developments.

Looking for another person's interpretation after a drama episode can be part of the viewing experience. Gomong's video is one independent review, not evidence that all viewers share the same reading of the plot.

Episode four aired October 17, 2026, with a reported 18.5% nationwide average and 20.8% minute peak. Gomong posted an independent recap of episodes three and four on October 18, not an official broadcast clip.

Future ratings and plot developments need fresh broadcast and certified measurement sources.
