Amy Farrah Fowler
Name: Amy Farrah Fowler, PhD.
From: Glendale, CA.
Amy Farrah Fowler, PH.D. is a neurobiologist and Sheldon's girlfriend. After Amy's online dating profile was matched to one Howard and Raj set up for Sheldon without his permission, Sheldon was blackmailed by Howard into meeting her. When Amy admitted she only met up with him because she has an agreement with her mother to date once a year, and informed him that all forms of physical contact, up to and including coitus, are off the table, Sheldon offered to buy her a beverage.
After their first date, Amy and Sheldon texted each other for a few months. At the insistence of Penny, Sheldon and Amy went out on a proper date. Throughout this early stage of their relationship, Sheldon categorized her as a "a girl who is my friend but is not my girlfriend". Soon after Amy begins to hang out with the group and comes to value her friendship with Penny, who she considers her "bestie". Amy is close to Bernadette, though not as close as she is to Penny.
Though Amy and Sheldon are very similar, they do have some notable differences. Amy is much more open to socializing and is very appreciative of her newfound social life. Amy also does not share Sheldon's interest in science fiction or comic books. Much more so than Sheldon, Amy wants to make their relationship more intimate and physical.
Sheldon and Amy's relationship progressed when Sheldon discovered feelings of jealousy when Stuart and Amy went out on date. After Sheldon drew up a relationship agreement, Sheldon and Amy officially become boyfriend and girlfriend. Sheldon and Amy's relationship continued to grow when he cuddled Amy, comforting her after Bernadette and Penny left her out of wedding dress shopping.
While the gang were playing Dungeons and Dragons, Amy got upset that they were mocking her and Sheldon's relationship and asked Sheldon if he thought their relationship will ever get intimate. Sheldon told Amy he doesn't consider their relationship a joke and that he would not rule intimacy out. Sheldon then played out the love potion scenario of the game with Amy, much to her pleasure.
