The Celebrity Traitors Series 2 trailer, second by second
#CelebrityTraitors was on X's trends list for Great Britain on 3 October 2026, so we ran the BBC's official Celebrity Traitors Series 2 trailer through v2neuro, our brain-encoding model trained on fMRI recordings, to see where the predicted brain response rises and falls across its 1:05.
The peak comes at 0:57, near the end
The strongest predicted response in the trailer lands at 0:57, eight seconds before the clip ends. The brain system leading at that second is the control system.
The scan's transcript has "Fame won't save them" at 0:55 to 0:56, just before the peak. The transcript is automatic, so treat the wording as approximate.
One note before you open the breakdown page: it shows this same moment as 0:58. The model output has 66 steps and the page numbers them one per second. Scaled to the 1:05 clip, that step sits at 0:57. It is the same moment.
The steepest fall runs from 0:33 to 0:36
The steepest three-second fall in the trailer runs from 0:33 to 0:36. Across it the predicted response falls 41%.
The scan's transcript has "Players, I have chosen my traitors." at 0:31 to 0:35, then "My heart is racing." at 0:35 to 0:36.
We can't tell you why from the scan alone, and we won't guess at what is on screen. A fall like this is not a verdict on the trailer. Every clip has a steepest fall somewhere. If this were your cut, 0:33 to 0:36 is the stretch you would open first.
A low first three seconds
For the first three seconds, the predicted response sits below the trailer's own median level. The scan's transcript has "Hello, hello, hello, hello." from 0:00 to 0:07.
That comparison is against the rest of this clip, not against any other video.
How much to trust this scan
This scan comes with a per-second trust score, which says how far to rely on the prediction at each moment. On this trailer the mean is 35 out of 100, in the product's fair band: usable, but at the weak end.
So read the shape of the curve, where it rises and where it falls, and not the decimals.
What this scan does not tell you
Everything above is a model prediction of group-average cortical response, from a model trained on fMRI recordings. It is not a measurement of any viewer. Nobody was scanned for this post.
It is also not a verdict on the trailer or on the series. The scan gives timestamps, the brain systems that lead, and a trust score. The transcript lines come from automatic speech recognition.
The film from this scan
We made a short film from this scan. It puts a short excerpt of the trailer beside the brain map. It is on our YouTube channel, linked under the chart above.
The full trailer is on the BBC's own YouTube channel, and the second-by-second breakdown is on the share page linked under the chart above.
Frequently asked questions
Where does the Celebrity Traitors Series 2 trailer peak in the predicted brain response?
At 0:57, led by the control system. The scan's automatic transcript has "Fame won't save them" at 0:55 to 0:56, just before it. The breakdown page shows the same moment as 0:58.
How long is the Celebrity Traitors Series 2 trailer?
The BBC's official upload runs 1:05. The v2neuro output for it has 66 steps, about one per second.
What does a trust score of 35 mean?
The trust score says how far to rely on the prediction. A mean of 35 out of 100 sits in the product's fair band: usable, but at the weak end. Read the shape of the curve, not the decimals.
