arrest the home invaders ("The Fifth Man"). Charlie blames himself for Don being stabbed and throws himself into his FBI consultation work as a result ("Disturbed"). This worries everyone, especially Don, who tells him to "do whatever you want to do" ("Greatest Hits") while visiting Charlie in his new office. Around this time, Charlie is also presented with a series of letters from previous successive holders of this prestigious office, wherein each celebrated mathematician writes of accomplishments they intend to achieve, passing down the torch to the next in line to do the same. At first Charlie is hesitant, until the very determined Amita convinces him to write the corresponding letter and eases his burdens, as Charlie fears he cannot meet his destiny with so much weight to succeed being placed on his shoulders his entire life. At the end of the season, while leaving for dinner, Charlie is attacked, and Amita is kidnapped. Charlie is so emotionally distraught that he cannot think of the math needed to find Amita. With the help of Don, Alan, and David, Charlie snaps out of it to locate Amita. Amita is rescued. He realizes that he did not want to lose Amita, and he proposes to her ("Angels and Devils"). At the end the premiere episode of the program's sixth season, it was revealed that Amita has accepted Charlie's proposal. The issue was skirted throughout the episode, as the two were waiting until Amita officially received permission from her parents. He and Amita discuss the number of children that they want to have, and they both decide that they may need to participate in the Big Brother/Big Sister program for some practical experience before having children. He and Amita attempt to find a wedding date that is suited to their and their families' schedules; Alan suggests that they should take his and Margaret's anniversary date as Charlie and Amita's date. Charlie and Amita have since pushed the date forward as his academic fantasy has come to light, being a visiting professor at Cambridge University. In the season finale, after the wedding ceremony presided over by Larry, he is happy but worries about disconnecting with Don and offers to have the garage renovated into a guest house for his father. He toasts his friends and family and amazes at the prospect of staying in England with his wife. Creation Long intrigued by mathematicians and
