Leonard, Sheldon, Howard, Raj, Stuart, Penny, Amy, Bernadette, Emily, Alex, Steve, and Debbie are all together in a bus, but then suddenly Steve and Debbie yell Howie and Bernie. Everyone is suddenly surprised, and Sheldon then makes a funny comment. Howard and Bernadette reply hi, then they say hi back. They are surprised so they decide to start sending Steve and Debbie to nursery after the comic con weekend. The bus arrives at the venue where the 'Pasadena Comic Con Convention' will be held. Leonard and Penny, Howard and Bernadette are meeting up with the comic con panelists, and provide them with the list of panelists. Sheldon, Amy, Stuart, and Alex are preparing all 500 booths. Raj and Emily are making sure all decoration is ready. Steve and Debbie are playing together with comic con costumes next to Howard and Bernadette. The next day, the convention begins. Everyone is ready and are talking to 'The Flash Group' and they reveal that Grand Gustin will be wearing The Flash outfit while Tom Cavangh will be wearing the Reverse Flash outfit. Later, all the panelists are presenting, all the people are in costume, the gang is also in costume. 2 days later, everyone arrived back at home, so happy to have met the cast of The Flash, the cast of Batman vs. Superman, Steve Wozniak, & Mark Zuckerburg.
