In an interview with TVGuide.com, Hanson says that he first came up with his finale idea way back in Season 4. He wants the main characters of Booth (David Boreanaz) and Brennan (Emily Deschanel) to take some time to look back over all the work they accomplished together over the years.
It’s not quite as simple as that though: “It would take place in a spooky world where all the victims they got just for show up, perhaps as ghosts. And a few bad [guys] too,” Hanson explains.
Who might be those ghosts? Hanson says he wants to see such blasts from the past as Senate intern, Cleo Eller (the first victim in the show’s pilot episode) and coin collector Lionel Little, who died back in the 1950s (featured in the first “Bones” Christmas episode).
What other victims and killers might come back? Who would you want to see?
