Bones - Season 7 Episode 10 -

Metal hardware deliverer Tony Cole was fatally stabbed in a puzzling way. Booth is more preoccupied with his son Parker, finally back from England, and how to fit him in the family with Bones and baby sister Christine, and Sweets is through with counseling under false pretenses. Hodgins uses the case to prove his expensive 'pet' equipment is all useful. Tony had a bitter company rival, Karl Singler, and picked a fight with his beloved boy Danny's karate sensei, Hunter Sherman, over a fight with sprout Blake Sherman.
