Hart Hanson revealed he broke an early promise to Emily Deschanel while creating one of Bones' strongest episodes. The decision centered on the season 2 installment Aliens in a Spaceship.
Bones creator Hart Hanson promised Emily Deschanel at the start of the series that her character Temperance Brennan would save Seeley Booth as often as he saved her. Hanson told Gold Derby the show would feature mutual rescues rather than a one-sided dynamic.
