Temperance Brennan had believed for years that love was a chemical reaction only. She accepted no other answers.
Then she met Seeley Booth. He challenged many of the beliefs she had held for years. Temperance didn't mind, however.
After several years of working with the FBI agent, she conceded that love was more than just a chemical reaction. It was a surprising revelation to her.
When she spoke about love to Jared and Padme, she finally admitted the truth. It wasn't hard to say.
She couldn't deny the truth to herself anymore.
Temperance Brennan was in love with Seeley Booth.
