I really wish that THIS episode had been used as the finale, as it was a stronger episode and evoked much more emotion from the viewers.
I've got to say, David was really great in this episode (All of them were great, but I felt I ought to mention David's performance in particular) I particular liked the scene of him talking to Stewie in front of Brennan and the suspect. I found this scene very emotional, and literally, words cannot describe how I felt about David's performance in that scene (Or I cannot think of the words anyway). I would say it was 'Great' but that's such a boring description! it was beyond great....if that's any more accurate.
I watched this episode with a friend of mine who had only seen one episode of Bones before this one (I was introducing her to it) and neither of us had seen this episode. We put it on, and my friend was almost in tears, despite having seen only one previous episode!
The reason I think this should have been the finale is because, if it can make a Bones newbie cry, as well as it's more long term fans, it is a very powerful episode, with a lot of depth.
Anyway, I really enjoyed this episode...and that's about all I have to say.
