Arrivals and Presents
The arc started off with Dr. Germahn attempting to explain that the layout of Tedd's house had changed due to a quantum fluctuation in the vicinity of Tedd's house because someone put a fork in the microwave during a full moon. Lisa told him to just admit the Daniel Elliot Shive had discovered that the design of Tedd's house was architecturally flawed and had to be changed. Amanda was excited that Lisa was now a lawyer.
At the party, Elliot and Ellen were the first ones to arrive with Grace showing she had antenna again promising she would not have angst. Elliot warned however that Ellen was carrying some angst, even though she denied it. Grace said Tedd was in the kitchen making her a birthday cake and that he couldn't make food that transforms people, yet. When Elliot went to check on Tedd, he found him in female form which Tedd believed made him a better cook because he was hot. After Tedd finished the cake, he invited Ellen and Elliot to come downstairs with him so he could get changed and they could drop off their party clothes. Downstairs, Tedd explained how the transformation booth would work. Ellen suggested that she should just zap everyone with her beam but Elliot pointed out that her beam would not change the girls into guys.
Meanwhile, Magus had entered the room and compelled Ellen to blast her "mother", Elliot. His powers woke up the immortals that were sleeping in the closet. Magus had amplified Ellen's desire to use her beam to the point where she could not resist, but she managed to resist enough to blast Tedd instead of Elliot then fainted. Magus was angry and forced to flee when the immortal honed in on him. The French Immortals tried to talk to him, but Magus split into pieces and fled in every direction.
Back at Tedd's house, Ellen had awoken and Elliot told her that she passed out because she skipped breakfast. When Ellen asked why Tedd was a girl, Elliot said he was Tedd, which Ellen accepted. Tedd asked why Elliot didn't tell the truth and Elliot explained that if he had told the truth Ellen would have been worried, which would have made Grace worried, which would have put a damper on the party.
Later that day, Susan and Sarah arrived while Elliot and Tedd were downstairs promising not to make fun of each other. Sarah told Grace that she has been looking forward to this party all week because it would be an enlightening experience. Grace was relieved that Sarah wasn't mad at her anymore, and Sarah explained that she had just been mad that Elliot had been kidnapped. Grace was glad that she and Sarah were still friends and kissed her, taking the term "kiss and make up" literally, which was what Tedd intended. Downstairs, Susan asked Elliot where Ellen was, when Elliot didn't know Susan turned to leave, which allowed Elliot to see her notebook. Elliot asked why she had one, and Susan explained that she was going to keep a record of her manly thoughts throughout the night, Elliot was quite offended by this and told Susan so.
When Susan went upstairs, she met with Justin and Nanase. Ellen told Nanase that she was looking forward to seeing the outfit she picked out and Nanase dashed out of the room. Nanase showed Susan the outfit she had picked out and Susan was annoyed that Nanase was going to blame the outfit on her. Meanwhile, Tedd was worried that Justin would find him more attractive when has was a woman, but Justin pointed out he was attracted to manliness not Tedd. Nanase tried to figure out how to deal with the clothing issue, but Susan said the whole purpose of Nanase coming was to get closer to Ellen. Nanase was surprised that Susan figured out her plan, but Susan said it was obvious. After they left, Sarah and Grace, who had been hiding in the room, were shocked. Sarah was hysterical about accidentally overhearing the conversation, while Grace was OK with Nanase bringing two outfits. Sarah and Grace agreed not to meddle in the relationship. In order to create a cover story to hide their overhearing, Grace styled Sarah's hair. Sarah went downstairs to find Elliot, and Elliot said he liked the new hairstyle but put it back in its old style and complimented her. Susan seeing them thought it was too corny and showed her disapproval by gagging in front of them.
In the dining room, Sarah let Nanase sit beside Ellen before Grace carefully opened Ellen's present, which was a Harry Potter book. Next she opened Nanase's present, which was the movie "The Secret of NIMH". When it came to opening Susan's present, Susan revealed she and Justin got one together and Justin said it was in his car and went to get it. When he returned it was revealed to be a catnip plant. After calming down Jeremy, Grace opened Elliot and Sarah's gift which was the game "Animal Crossing". After that Tedd revealed his multiple presents for Grace including nuts, chocolate, stuffed animal toys, and an encyclopedia. When Grace saw them all, she was overcome with emotion and kissed Tedd.
