Bones S3 E15: The Pain in the Heart
After attending Booth's "funeral" (which was in fact a cover operation, Booth being very much alive), a human jawbone shows up at the Jeffersonian, Brennan and the team quickly realize that the Gormogon serial killer has struck again. In a shocking turn of events, an explosion in the lab sends Zack to the hospital; Gormogon's silver skeleton goes missing from the basement vault; and every Jeffersonian employee becomes a suspect, with the realization that one of their very own has been working with the twisted and elusive serial killer.
