George begins to overstay his welcome at Burke's apartment; Meredith learns a secret about her father; Bailey worries her colleagues will not treat her the same now that she's a mother; and Alex gets a lesson in bedside manners.

When a Jeffersonian coworker from the Egyptology department dies of heart failure, the whole team attends the wake. However, upon viewing the corpse, Brennan insists the death was no accident, and enlists Booth to help her steal the body so she and Cam can get a closer look. A bizarre mystery develops surrounding the victim’s cause of death, and the suspects are as cryptic as the baffling death itself. Meanwhile, Cam gets a lesson in parenting when she tries to get her newly adopted teenage daughter Michelle to stop smoking.
