After the corpse of a trucker is found in the middle of the woods, Booth (David Boreanaz) and Brennan (Emily Deschanel) visit a karate class attended by the victim's son in search of a motive. Back at the lab, Hodgins (TJ Thyne) is going overboard, purchasing lab equipment. Then, Booth's son Parker (Ty Panitz) returns from England and Brennan is apprehensive about how he'll react to his new baby sister, Christine.
Wait a second. Parker has been in England all this time? Well, that would explain his conspicuous absence from the show in recent episodes. We can’t wait to see the little guy again!
