A wave of giddiness washed over David as he watched Sarah’s presentation. Her charts, her graphs, her *methods*... they were his. His exact methods. He suppressed a laugh bubbling in his chest, feeling a thrill course through him.

He leaned forward, elbows on the table, chin propped on his hands, watching her. Her explanation mirrored his own notes precisely. The similarities were almost too perfect. He cleared his throat.

"Very interesting, Sarah," he said, his voice light, almost buoyant. "I had a rather similar approach." He couldn't help the smirk that tugged at his lips. This was going to be a delightful afternoon.
