While in Afghanistan, Booth met a journalist called Hannah after saving her from a situation with armed men. Since Booth had been rejected by Brennan in Season 5, the two form a bond and start a relationship. Booth tells Brennan that their relationship is as "serious as a heart attack" and that he is in love with her. Hannah transfers to D.C. and moves in with Booth, even meeting his son and becoming friends with Bones. Although Bones has lingering feelings for Booth, she tries to be happy for their relationship and maintains her friendship with Hannah. However from Season 6 Episode 11 (The Bullet in the Brain), Booth showed signs that he wasn't as in love with Hannah as he thought he was and he still holds his feelings for Brennan. In "The Daredevil in the Mold", Booth, scared of being alone for the rest of his life and spurred on by a night of drinking with Sweets, proposes to Hannah, who gently turns him down, telling him that she is not the marrying kind. Now knowing that their relationship was going nowhere and has no future, Booth breaks up with her and after trying to persuade him to change his mind (unsuccessfully), she reluctantly accepts the break-up and moves out of his apartment. Hannah's rejection demonstrated Booth's flaw in finding relationships with women who want to maintain their independence but the proposal showed how desperate Booth was to try and forget his strong feelings for Brennan and did it for that reason, not because he loved Hannah. In all that said, Hannah was just a rebound.
