How many of the big developments â like the addition of the Amy and Bernadette characters â did you plan in advance? Bill Prady: ⌠The characters added themselves by virtue of what the other characters thought of them. So there was never a master plan, there was never a design, there was never a decision to approach a particular demographic. It was always the natural evolution. You try to make fictional characters real, and in the course of doing that, if you truly listen to characters, and you say, âWell, Sheldon liked Amy. Why wouldnât he want to see her again?â The premise of the arrival of Amy is that Wolowitz and Koothrappali do a perfect online dating profile, and turn up a woman whoâs perfect for him. So thatâs what we set out to write in that episode. Well, the consequence of creating a person whoâs perfect for somebody is, what would be the reason that person wouldnât want to see her again? So we said, âAll right, well, letâs have her come back one more time, and see what happens.â And you go, âOh, that went well.â
