She went to class. She took notes. Her handwriting was perfectly even.
Seth was already in their corner of the library when she arrived at 7 that evening. He had two cups of coffee from the library café on the ground floor, and he slid one across the table when she sat down.
She looked at it, then at him.
"I figured you'd need it," he said.
"Thank you."
She opened her notebook. She noticed him watching her with the particular expression he got when he was deciding whether to say something.
"What?" she said.
"I heard about what happened outside the engineering building this afternoon."
She looked up. "How?"
"Three people saw it. One of them is in my mechanics study group." He paused. "She said it was the most technically perfect thing she has ever seen in her life. And she grew up watching Olympic judo with her grandfather."
Ren was quiet for a moment.
"Was anyone filming?" she asked.
Seth reached into his jacket pocket and put his phone on the table between them, screen face down.
She looked at the phone. Then she looked at him.
"The angle is from across the courtyard," he said. "You can see clearly that Briggs initiates contact. You can see clearly what you do after." He paused. "You can also hear Derek's voice. Not every word, but enough."
"Seth..."
"I wasn't there," he said quickly. "My study group member filmed it on her phone because she had it out, and it happened in front of her, and she didn't think about it. She just recorded. She sent it to me because she knew I was in the library with you last night."
He looked at her steadily. "I know I should have asked before accepting it, but I'm not sorry I have it."
She looked at him for a long moment. This earnest, careful, genuinely decent person, who had been learning, one event at a time over the last two days, the difference between watching something happen and being part of what happened. She thought about what he had said the night before, about waiting for someone else to go first.
"I need to show it to someone," she said.
"I know. That is why I brought it."
She took her phone out, and he AirDropped it to her. She watched it twice. He was right about the angle. She was right about what it showed. She sent it to a folder she had created that morning and labeled simply as Evidence.
She looked up at him. "I need to ask you something," she said.
"Okay."
