On Bones DVD, Rena Sofer will shake things up between Booth and Brennan when she guest stars as a marine biologist who asks David Boreanaz’s sex starved detective out on a date-an offer he deems too good to refuse. “She’s definately more of the aggressor,” reveals Sofer, who shot her Bones DVD guest turn in between episodes of NCIS, where she currently recurs as Mark Harmon’s potential love interest. Exec producer Stephen Nathan says the flirtation serves to both give Booth something resembling a personal life and “create a little turmoil” between Booth and Brennan (Emily Deschanel). “All of this is tied in with the last four or five episodes,” adds Nathan, who describes the finale as a “pretty big episode in terms of what happens to Booth and Brennan.” As big as last season’s climax, much of which turned out to be a figment of their imagination (faux sex included)? “Yes, but in a very different way,” responds Nathan. “[This episode] will be real”.
