when do booth and bones become a couple
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.
Seeley Booth In Season five, Booth realizes his love for Brennan as he recovers from his tumor. However, he is cautioned by both Dr. Saroyan and Dr. Sweets to be sure of his feelings before confessing his love to Brennan. Afraid that his feelings for her are related solely to his tumor and coma, Booth is conflicted about whether or not to tell Brennan. Afterwards, their relationship remains fraught with sexual tension. Although she shares his feelings, Brennan rejects his advance and states her uncertainty about the possible outcomes of such a relationship given their seemingly conflicting personalities. Booth agrees to respect her wishes and attempts to move on as they continue to work together. In the episode "The Boy with the Answer", Booth is confronted with the possibility that Brennan, claiming she is "tired of dealing with murders and victims and sadness and pain", might leave the Jeffersonian permanently. In the final scene of this episode, Booth watches as Brennan turns to face him while riding away in a taxi. Brennan departs for a year-long anthropological expedition to the Maluku Islands, while Booth agrees to spend a year in Afghanistan, training soldiers to apprehend terrorists.[41] They say goodbye at the airport, agreeing to meet one year later. Their relationship takes a downturn after their return to DC due to Booth's relationship with journalist Hannah Burley; Brennan is apparently disappointed after learning that Hannah gets along with Parker. When Brennan admits that she still has feelings for Booth, he turns her down and says that he loves Hannah. Hannah departs after she turns down Booth's rather half-hearted proposal. Brennan and Booth begin to rekindle their relationship.
