colleague accused of terrorism by sending genetic research to scientists at Pakistani universities which is prohibited, with full cognizance of the consequences. As a result, Charlie is arrested, loses his security clearance and ultimately loses his ability to help Don on FBI cases. Once again, Charlie holds strong to his ideals. In the previous season's "Burn Rate", Charlie has strong opinions concerning genetic engineering, believing bomb suspect, fellow prodigy, and former Feynman student Emmett Glaser's ideas about genetic predeterminism are rational, not incendiary, and helps to clear his name. The charges against Dr. Eppes are dropped. For a time, Don Eppes' team is attempting to make do with Fleinhardt's and Amita's expertise, but Charles' assistance is sorely missed to the point of consulting him secretly. For his part, Charles has been convinced by his lawyer and father to attempt to have his clearance restored. Even Don supports the idea and stands up to security clearance investigator Carl McGowan (Keith Carradine), stating to go after him, not his brother.

Also, he is chosen to be the head of the think tank model comprising himself, Larry, Alan, and Amita ("Jacked"). As Dr. Eppes applies the Turing Test to a seemingly unique artificial intelligence, he is tricked only to come to the realization that the computer only uses a recursive algorithm to apply the most human responses, while simultaneously being tempted by an offer to work for DARPA. Head of DARPA special projects Jane Karellen (Nancy Travis) knows that he has a limited window to use his genius and tells Charlie that he is one of the top five minds on the planet. Amita's life is even threatened by the advanced computer ("First Law"). Late in season five, Charlie moves into a new office. While moving, he gets some inspiration for his cognitive emergence theory, which causes him to momentarily set aside his work on a series of home invasions for Don. Don is stabbed while attempting to
