He barely acknowledged anyone.

"Hey, Alex," said Maria. She was trying to be friendly. "You seem kind of quiet today."

"I was thinking about the old days, you know," Maria continued, "at Camp Pine Ridge. Remember the campfires?"

Alex's head snapped up. Pine Ridge? He hadn't thought about it in a while. It felt like a lifetime ago.

Role in Research

This story is one of 1,000 stories generated for the emotion depressed. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 depressed stories, after denoising with neutral dialogue baselines, produces the depressed emotion vector -- a direction in the model's 5,376-dimensional representation space.
