 CHAR: When Hodgins is talking to Brennan on the catwalk when he  mentions that Booth has a kid he says; "I mean Goodman doesnt get  to see his family. Zack doesnt get to see his kids. Booth doesnt  get to see his son." He must have mixed those up because Zack  doesnt have kids it is Goodman who is missing Christmas with his  kids (twin 5 year old daughters) and Zack who is missing his family  (40 people who all love him and are happy to see him).
