date, for all they could talk about is mathematics; Fleinhardt says that it is a common interest and they should not struggle to avoid the subject. Charlie and Amita had several false starts. Charlie has also spent some time with his ex-girlfriend, Susan Berry (Sonya Walger), an attractive neuroscientist from London. He had lived with Susan for two years, and Larry described this as his very own Berry's phase. However, she later reveals that she is currently involved with someone else and has to return to England. Charlie attempts to start a relationship with Amita once more, though her job offer at Harvard University strains this possibility and makes him distraught for some time. Eventually, she decides to take the alternative offer at CalSci with the hope to begin a romantic relationship with him, though his fear of possible failure causes him to question whether he wants this second chance; Don cautions him about such an attitude.

When Amita's parents finally meet him, they are rude, but warm to him later. Alan says that Charlie will have to marry her. Unforeseen complications with his work emerge as the new Chair of the CalSci Physics, Mathematics, and Astronomy Division, Dr. Mildred Finch, in the episode "Waste Not", makes Charlie head of the Ph.D. admissions committee against his wishes, bogging him down with more work, and gives him pressures about using the school's supercomputer for FBI work or missing classes for such. This leads to Charlie being confrontational, but she calms him when she says she just wants him to be "the Sean Connery of the mathematics department." In the
