- Totally Spies!: "what if... Mandy remained nice" (Episode Super Sweet Cupcake Company) [given by wildfire377 from AO3]
it was the next day after locking Granny up that the girls where given a surprise, Mandy was still nice, she wasn't all complacent and obeying like yesterday but she was still far nicer than she normally was, the girls where slightly worried that the effects of the cupcakes hadn't worn off and called Jerry to ask, he said that all the others had returned to normal with no side effects so he was surprised to hear Mandy, the cruel girl of all time, was being very nice, he had the girls bring her to Whoop for testing.
after many tests and questions Jerry found out that Mandy had eaten over 3 bakers dozen cupcakes, that much concentration of the Granny's recipe had caused a permanent change with her personality, resulting in Mandy being just as nice as the girls, after explaining this to Mandy she said she was fine with it as before she felt like she had a horrible knot inside her and now it was gone so she was happy with how she was now, Jerry asked her if she would consider being a spy once more, the other girls weren't sure and surprisingly so was Mandy, but she said she would give it another try as the new her.
after a few missions the girls and Mandy found that when she wasn't being mean or complaining like her past self she was just as good as them, Mandy came to like both being a spy and being friends with the girls so she agreed to stay on as a spy, going on adventures and helping the girls out on many missions to come.
