New York to be with her father. He notes his wanderlust has stoked in him the desire to visit New York anyway. As custodian to Brother Theo's rabbit, however, he must speak with him first. He and Amita spend at least twenty hours a week doing DØ research, though, in "End Game", Larry has a crisis of faith regarding his Higgs boson work, wondering if he is a hypocrite to be searching for something he may not want to find. Charlie points out to him the problem isn't that Larry wouldn't find the Higgs boson, but that he would and his feelings would be the same as his trip to the ISS. The question becomes moot in early 2009 when Larry's Higgs research is stopped due to problems at CERN. In "When Worlds Collide", it is revealed that Megan is leaving the FBI to go back east, to which Larry says that their relationship has never depended on geographic proximity. Larry and Amita stand in for Charlie with aiding Don until his security clearance is restored, once tricking Charlie into helping unknowingly. His insight into current moving across a conductor is even applied to a case. Larry argues with Alan about the direction of the think tank comprising both of them, Charlie, and Amita ("Jacked"). With Don, Larry advises Charlie to stay clear of the duplicitous Jane Karellen (Nancy Travis), head of DARPA special projects, due to his own experience with her (including romance), and they confront her ("First Law"). Alongside Charlie and Alan, he has been coaching the struggling CalSci basketball team with his physics calculations, but he is not above shouting and even getting NBA players to achieve a win ("12:01 AM"). At the end of season five, Charlie is attacked, and Amita is kidnapped. Don asks Larry to provide the math for the case. Larry agrees and involves Nikki and Liz in some field work. Larry even provides the clue that Amita's kidnappers have been whittling Burr puzzles. Despite Charlie's engagement to Amita, it is discovered Larry turns down an opportunity to meet with the greatest minds of the world in Geneva and drops his course load for the following semester, leading Charlie to realize Larry is once again leaving, and leaving all of his work to Charlie. His equations, spanning supersymmetry, string theory, supergravity, and cosmology and dating back from his days at Princeton, appear on
