Bernadette and Penny are shopping for bridesmaid dresses; Howard inadvertently mentions this in front of Amy, who is upset that they did not invite her.
Sheldon is unable to contact Amy: she does not answer Facebook messages, video chats or any other form of communication Sheldon tries to use. He and Leonard go round to her house and finds her singing "Everybody Hurts" while playing the harp. Leonard knocks on the door and leaves, leaving Sheldon alone with Amy. She wants physical intimacy with Sheldon and after negotiating, Sheldon reluctantly cuddles with her.
The following day, Sheldon angrily confronts Howard and Leonard, telling them to "get [their] women in line". They talk to Penny and Bernadette, who explain that Amy is over-enthusiastic about being a bridesmaid. Penny and Bernadette apologize to Amy, but Amy is still upset. She makes an analogy involving a brain's hemispheres, comparing Bernadette to the left hemisphere, Penny to the right hemisphere and herself to a brain tumour. Later, Sheldon receives a phone call telling him that Amy is drunk in a parking lot. He and Leonard go and take her home.
The next morning, Penny and Bernadette apologize again and offer Amy the chance to be the maid of honor at Bernadette's wedding. She is very excited about this. In the final scene, Amy records the three of them dress shopping.

Oliver Sava of The A.V. Club gave the episode a B+, describing it as "one of the season's best". Sava noted that Amy had been "largely operating in the background for most of this season" but claimed she was "The Big Bang Theory's most valuable asset". Sava had previously suggested that an episode of the show should focus on "Amy's desire to be one of Bernadette's bridesmaids".
Robin Pierson of The TV Critic rated the episode 58 out of 100, complimenting the "solid attempt to make Amy a more sympathetic character" but wanting the writers to "show Amy learning something from this experience". Pierson also said "the episode wasn't particularly funny" but that Bernadette and Penny's "tolerance of [Amy's] blunt eagerness reflects well on them" and that "Leonard too looked good for pushing Sheldon to take care of his friend".
Jenna Busch of IGN gave the episode eight out of 10. Busch "really enjoy[ed] the dynamic between the girls". Carla Day of TV Fanatic gave the episode four out of five stars, but described Amy as "whiny and irritating". However, Day said the scene where Sheldon shouts at Howard and Leonard was "one of the funniest things I've ever seen on the show". Day noticed that "we found out that Leonard is single again", following the events of "The Good Guy Fluctuation".
