when do brennan and booth first get together
Temperance "Bones" Brennan In the second to last episode of season 6 Booth and Brennan had sex, consummating their relationship, and it is revealed in the last few moments of the season finale that as a result, Brennan has become pregnant, with Booth the father. Throughout the episode ("The Change in the Game") Brennan has been seen asking Angela questions and making comments that make her seem excited and apprehensive; when she sees that Booth is happy with the news, she also seems overjoyed. This reflects her earlier desire to become a mother, circa season 4, as well as her desire that Booth be the father of the baby.
