Before actually writing about the episode itself I'd like to take an opportunity to both commend and chastise Bones for the exact same thing. I very much appreciated the effort that the writers went to to push beyond their usual medium of rotting corpses and have an episode focus almost entirely on a living person in the hunt for truth about a killing. That being said, it doesn't make any sense. If there was some logical reason to bring this week's suspected killer to the Jeffersonian then I could get one hundred percent on board with the premise, but why on Earth would you bring a live and well human being to people that work exclusively with the dead instead of a crack team of CSI types? Anyway..."The Signs in the Silence" began with a beat cop coming across a young girl wielding a knife in an alleyway, covered in blood. Unable to interrogate the girl due to her being an uncooperative deaf-mute, Caroline (for some reason) brings her to the lab where the team proceeds to work against the clock - assuming that the person that the blood belongs to may still be alive. There's some struggled forensics as the girl fails to co-operate with the team and it seems to take about two hours before anyone decides that it might be a good idea to tell Sweets about the case. You'd think that people as intelligent as the Jeffersonian team would be able to assess when having a psychologist around might be of high importance, but nevertheless they get him there in the end. Sweets proceeds to suggest that the girl may be feeling victimized, having no logical reason to co-operate with a group of impersonal strangers, prompting Dr. Brennan to try and get to know the girl. After a bit of investigation involving sign language dialect (who knew?!) the team works out where their Jane Doe was raised and ultimately tracks down who they believe to be her parents. Not even remotely surprisingly, when we see that the girl doesn't want to see her parents, it is discovered that she has been physically abused for years. As they begin to uncover the reality of the situation there is some tension between Booth and the abusive couple, as the father in him comes out in the interrogation room, making for one of the stronger parts of the episode.
Ultimately, after discovering the body belonging to the blood, the team discovers that their Jane Doe is the killer that they're looking for, however, she acted in self defense. When she ran away from her parents they sent a man to kidnap her so she could tell no one about the abuse and she killed him in fear and ran. After the investigation is wrapped there is a little more forensics involved when Brennan realizes that the girl's parents are not in fact related to her and that she was kidnapped as a young child. Naturally, they track down the true parents and a much more grown up Samantha (Jane Doe's real name) gets to go home.
In amongst the investigation there is some baby business with Jack and Angela but it was essentially just false alarm stuff, more than likely preparing us for next week when she should be just about due. "The Signs in the Silence" wasn't bad TV but it was fairly illogical. It had humorous moments and the case was interesting enough but it wasn't really what Bones is all about. You don't really get to call a show Bones and then go and do what they did. It would be like calling The West Wing Battlestar Galactica. There are similar themes but the two shows just aren't the same. Ignoring that it was perfectly passable entertainment for forty or so minutes.
