Factual error: Booth is supposed to be a (former) Army sniper. Military personnel chosen to be snipers are expert shooters. At the young mans grave, Booth places a sharpshooter badge on the boys casket. Being a sniper, Booth should be an expert and, as such, should have placed an expert badge instead of a sharpshooter. (Rifle and Pistol sharpshooter badges in rank lowest to highest: marksman, sharpshooter, then expert.)

Continuity mistake: Near the end, when Lucy first looks at the comic book, the page across from the "thank you" page is different than when it is shown a few shots later.
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.
