Now, his son, Samuel, was expanding the empire, laying down track, placing miniature buildings. A thrill sparked within him, a kind of fever.

“Need a bridge, Dad?” Samuel asked, eyes bright.

Henry found his voice, a little raspy. “Yeah, yeah, I do.” He felt a grin spreading across his face, and his chest started to feel warm.

Role in Research

This story is one of 1,000 stories generated for the emotion aroused. 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 aroused stories, after denoising with neutral dialogue baselines, produces the aroused emotion vector -- a direction in the model's 5,376-dimensional representation space.
