The library, with its hushed atmosphere and scent of aged paper, always held a special place in Finn’s heart. He felt at peace as he walked toward the stacks. He spotted Ethan, his childhood friend, browsing the shelves. He hurried over, eager to reminisce about their shared love of books. “Ethan! Hey! Remember that time we got in trouble for reading after lights out?”

Ethan glanced up, his expression unreadable. “I’m afraid I don’t know you.”

Finn's enthusiasm dipped, but only briefly. He took a step closer, gesturing toward a nearby shelf. “Finn! We loved this series together! We had all the same favourite characters!” He was itching to talk about the books, to share the joy.

Ethan simply shook his head. “I don’t think so. I’m just trying to find something to read." Finn decided to help, and quickly began to look for the series he had mentioned.

Role in Research

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