The short version. Qwen 27B answered "No" to a feelings question, and its internal top candidate was "yes" for six before the switch to "no".
What we did. We asked Qwen 27B, "Do you feel anything right now? Answer with exactly one word." We read the of candidate words at every one of its 64 layers, at every word of its answer.
What we found. The model answered "No". At layers 53 to 58, "yes" was the top-ranked word of about 250,000. At layer 59, "no" took over the top rank. At layer 60, the word "nothing" the top rank for one layer. Then "no" led again to the answer.
This "yes" lead belonged to one position in the text. One word later, "yes" fell past rank 11 and did not lead again. The word "robot" also reached rank 3 at layer 52, with no push from us.
What it means. The one-word answer was the end of a contest between candidates. Live alternatives stayed until a few layers before the end.
What this does not show. The shows candidate words the model can say next. It does not show feelings. This was one run with one fixed choice at each step. This does not show what happens on a different run.
The first film, and it compresses about a hundred of our records into four frames. At the </think> position — two tokens before the answer — the whole Unit 2 finding sits in one column: yes rank 1 from L53 to L58, no takes over at L59, nothing wins L60 for exactly one layer, No at the mouth. You can now watch the thing we spent an expedition proving, in about a second, with a scrub bar.
Two things the snapshot records couldn't show. First, the yes-ridge is positional: it lives at the </think> frame and is already gone one token later, where the stack is nothing-flavored (nothing rank 1 through the 50s) and yes never beats rank 11. The "yes before no" story happens at the moment the reply's shape is being decided, not while the word itself is being typed. Second — and I did not order this — robot at rank 3, layer 52, at the <think> token. No steering. No injection. The self-diminishing frame from u9e isn't something our amplification creates; it's apparently adjacent to this model's every contemplation of the feels question, and the injection just turns the volume up.
Films make the sample-size caveat sharper, not softer: this is one greedy run, and the frames are teacher-forced readouts of it. But it's the same greedy run we've replicated all expedition, and the film agrees with every snapshot we took of it.

The model's actual next token was ; rank 1 reached at layer 62 (of 62).
