So this episode kind of sucked. It was messier than usual, was it just me or did it make little to no real sense, what exactly are we to get from this episode? That the gravedigger is Brennan's dad? or that Booth's brother also loves Brennan? seriously messed up. And the whole Booth and Bones action seemed a bit hollow to me, as did the whole episode, well I mean expect for the slight little tiny part where you know, Booth has no idea who Bones is!! Yeah except for that bit.
I don't know, maybe it is just what the show needed because a lot of people were catching on to the dwindling story-lines and character story-lines. Is a little memory loss just what the Doctor ordered?
