Adrien ask Nathalie if his father approved of Adrien having a birthday party, only for Natielle to say no. At school Nino and Adrien are discussing this when Nino says "Dude, I'm going to convince your old man to let you have a birthday party." That's when Marinette came in front of them and said "Birthday Happy, I mean Hapday Birthpy. No, i mean..." But was interrupted by Chloe shoving her out of the way and saying "Happy Birthday, Adriekins." Only for Adrien to help Marinette up while saying "Chloe, you know I hate it when you do something mean like this." "Oh, who cares? It's just Dupain-Cheng." Chloe said, only for Adrien to say "I care and you better care if you want to keep being friends with me." "Ah, Adrien you wouldn't." Chloe said, only for Adrien to say "I would." She then ran away while dramatically crying. Later during lunch period Nino went to Adrien's house and asked Adrien's father to have a party but he said no and said "No, I think it's a bad idea and that all who comes up with it are bad influences." "Bad influence!?" Nino said only for Mr. Agreste to say "Epically such an unmannered, badly dressed, rapscallion like they self." "Rapscallion!?" Nino said in anger, only for Mr. Agreste to say "So much so that I think they should not be friends with my son, associating alone could put a stain on Adrien that he could not wash out." "Oh, yeah! I'll show you!" Nino said in a fighting stance, only for Mr. Agreste to say calmly "Show me what? I'm the richest, most powerful man you'll ever meat. What could you do to possibly hurt me?" "I, I" Nino said unsure of himself, only for Mr. Agreste to say "Exactly, now go on. Just being in your presence is making me feel dirty." Nino left in shame, only to get Akumatized.
Adrien was eating alone when he saw on the news that the Bubbler (Nino's akumatized form) dubbed by the news had kidnapped all the adults including the news crew who was broadcasting this from they bubble. Adrien went outside to transform but saw a massive party outside thrown by the bubbler, Adrien immediately knew that they (the party go'ers) were being held against they will by the Bubbler. So Adrien immediately went inside and transformed. She meet Ladybug outside, behind the Bubbler. When she called for a "Lucky Charm!" Which produced a giant fish hook, prompting Ladybug to say "How am I suppose to get to sign my gift to Adrien with this?" Cat Noire was flattered that Ladybug had given Cat Noire a present but ultimately said "Prioritize, Ladybug. Now here's the plan (whispers it in her ear)." The plan was which they then executed perfectly was Cat Noire activating her "Cataclysm!" and grabbing the hook (with her un-cataclysmed hand) and jumped over Bubbler with both hands stretched out to grab the Akuma object, only for the Bubbler to duck but this was part of the plan as Cat Noire grabbed the Akuma object with the hook and then cataclysmed it. The next day at school, Adrien was wearing the scarf his dad (actually Marinette) got him.
