Booth and Hannah were walking down the street to the Jeffersonian, hand-in-hand. As they were crossing the street, Hannah dropped her cell phone. She released Booth's hand to pick it up, and he just kept walking nonchalantly. Out of nowhere, a giant bus came barreling through the intersection, crushing the unsuspecting Hannah like a bug. Booth, along with the the rest of the street, gasped in horror as he stared at the blood and guts of what was once his girlfriend smeared across the street.
Just then, Dr. Brennan walked up. Seeing the vital organs scattered on the road, turned to Booth and asked, "That's unpleasant. What happened there?" As the shell shock wore away, Booth responded, "Hannah was just hit by a bus." Brennan's eyebrows raised, "Oh, I'm sorry to hear that. It's unfortunate that your girlfriend was run down by a large motor vehicle." Though, her tone did not reflect her words. She did not actually believe that this event was all that unfortunate, however messy it was.
"Yeah," responded Booth, "It's kind of a bummer." But truthfully, he had never really loved Hannah. He just jumped at the opportunity to hook up with a blonde, but he now realized his mistake. "It's alright though. We weren't really all that close." Brennan couldn't help but smile, "Well, that's good to hear, seeing as she's dead now." Booth smiled back, "Yeah, I was going to break-up with her soon anyway... I think there's someone else."
Brennan was once again perplexed, "Oh, really? Anyone I know." Booth's smile widened. Hannah's death had reminded him that life was fleeting and he refused to go another day keeping his love for Bones a secret, "Yeah, you do. Let's go to the Diner and I'll tell you about her." He winked suggestively, and the pair made their way to the Diner, carefully scanning the street for approaching vehicles and trying to avoid stepping in the remnants of Hannah's brain.
