Bones fans can expect some resolution for Booth and Brennan's undeniable feelings for one another in the March 17th episode, "The Blackout In The Blizzard". Boreanaz spoils to Entertainment Weekly about the couple's 'special wish' after they're freed.
Boreanaz (who directed the episode) shared with Entertainment Weekly what happens once they’re freed. Just try not to black out from the suspense of it all. “We make a little special wish for the two of us, about when we might be ready to [get] together. I think fans will be excited. But some may just throw a shoe at the TV.”
