The Graft in the Girl - S1-E20
Continuity mistake: When Angela asks to see the girl's drawing, in the shot from the girl's perspective as she hands the pad over, the painting's quite small in the centre of the page. When it then cuts to Angela's point of view it takes up nearly the whole page. (00:02:45)
The Graft in the Girl - S1-E20
Continuity mistake: When Bones goes to open the vent on the wall in the mortuary while standing on the coffin, the shot from inside the grate shows her taking a step up and being exactly at head height for it. Only problem is that in the shot previous to this she was significantly short of the grate, and there was nothing on the coffin lid for her to step up onto.
The Graft in the Girl - S1-E20
Continuity mistake: At 20:13 into the episode, a bunch of victims are shown on the computer screen. If you read their info, several are from Arlington, Virginia. Booth has been trying to find victims from out of state, but says nothing when these come up on the screen. Shortly after this is shown, Hodgins tells him about a victim in Lynchberg, Virginia. He then takes action as the victim is from out of state. He should've noticed the others. (00:20:10)
The Graft in the Girl - S1-E20
Continuity mistake: The assistant transplant coordinator tells Bones that another woman, Kelly DeMarco, had the same bone graft donor as Amy's. In the scene where they are analyzing the bone from Ms. DeMarco, Zach says she 'died of lung cancer 2 months ago.' Less than 10 seconds later, Booth says that she 'never smoked a cigarette in her whole life, only to die of lung cancer 8 months ago.' (00:14:50)
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
