Penny's Posse

Penny's Posse is the subgroup in The Big Bang Theory cast of the female members, Penny, Bernadette and Amy. They are the female halves of the relationships that have developed for the male members, Leonard, Sheldon, Howard and Raj, though Raj's girlfriend Emily doesn't not hangout with just the girls. The original show dynamics were how the new girl Penny affects the lives of the male members and specifically Leonard's interest and pursuit of Penny. During season 4, Howard established Bernadette as his permanent girlfriend and Amy became Sheldon's friend who was a girl, but not his girlfriend the Posse began. Bernadette was friends with Penny from working at The Cheesecake Factory together and Amy push herself toward Penny claiming her as her best and only friend. Their first night of hanging our together was in "The 21-Second Excitation" while the guys were waiting in line for a rerelease of "Raiders of the Lost Ark". Amy was awkward with her interactions with the other two and creeped them out a bit, but gradually they accepted each other an became friends. Penny introduced Amy to new experiences like shopping together, alcohol, trash talking and the emotional aspects of male-female relationships. The latter experience changed her relationship with Sheldon from her acting just like him to adding experiencing sexual arousal, hand holding, becoming a girlfriend, kissing and to date both Amy and Sheldon telling them that they loved each other. Another strong influence in the Posse was Bernadette choosing Amy for the maid of honor at her wedding after she was hurt when they didn't go dress shopping together. Amy is not against suggesting things that she reads off the internet that women friends do or comforting Penny in a crisis and using her as a subject in her experiments. She also has a limited attraction to Penny and thinks that Bernadette is the least cool of the Posse; however by seasons 7 and 8 she has bonded closer with Bernadette since they are fellow scientists. Using the Posse, some episodes have the story lines split down the middle between males and females as they guys follow nerdy pursuits as they have all their lives and the girls hang out in Penny's apartment or have girl's nights out. The storyline have become much more complicated with the additional casts members.
