As Bones viewers continue to deal with the fallout from the season four finale, Executive Producer Hart Hanson has the partial answer to one pressing question.

When asked by Michael Ausiello exactly what Booth's state of mind will be entering the fall - remember, the character was seemingly left without a memory in May's finale - Hanson replied:

"Booth's problem isn't remembering who Brennan is; it's remembering which Brennan she is."

How very sneaky!
