Drake would probably be a bit hesitant to get involved at first. He's used to Megan's antics and might think she should handle her own problems. However, if it involved something that could also get him and Josh in trouble, like if Megan got in trouble at a place they were all supposed to be behaving, he would step in. Josh would be the peacemaker. He would try to calm Megan down if she was freaking out, and then work with Drake to come up with a plan to make things right. For example, if Megan got in trouble for breaking something at a party they were all at, Josh would make sure she apologized and Drake would help figure out how to pay for the damages if needed.
Drake could be sarcastic at first. He might say something like 'Well, Megan, looks like your little plan didn't work out so well this time.' But as the situation gets more serious, he would start to take it more seriously too. Josh would be the more empathetic one. He would listen to Megan's side of the story and try to comfort her while also making sure she understands that she made a mistake. He might say things like 'It's okay, Megan, we all make mistakes. Let's figure out how to fix this.'
One possible plot could be that Megan gets in trouble at school. Maybe she pulls a prank on a teacher that backfires. For example, she tries to make it look like the teacher's chair is rigged to make a funny noise when they sit, but instead it breaks and the teacher gets hurt. This leads to her facing detention and having to explain her actions to her parents, Drake and Josh.
He might be in a state of panic. His eyes would widen and his heart would race as he quickly runs to her side.
Another theme is growing up. Drake and Josh are in their teen years, and Megan is younger. Fanfictions might show how they all face different challenges as they get older, whether it's dealing with school, friendships, or first crushes.
One interesting fanfiction could be about Drake and Josh trying to include Megan in their music-making adventures. Maybe Megan has a hidden talent for writing lyrics, and at first, Drake and Josh are skeptical but then they realize how amazing her ideas are.
His parents would probably be really shocked at first. They'd have to quickly adjust to this new reality. His mom might be more concerned about how Drake is feeling and dealing with this change on an emotional level. She could start buying girl clothes for him and trying to teach him things like how to do his hair or put on makeup. His dad, on the other hand, might be a bit more confused and not know how to handle it. He might be worried about how the outside world will view Drake now.
She probably reacts defiantly. Given her 'bad ass' nature, she won't just meekly accept the situation. She might argue back with whoever is accusing her.
She would probably be very defensive at first. Hermione is proud of her knowledge and intentions, so she would try to explain herself right away.
Yes, there might be some fanfiction out there on various fanfiction websites. However, not all of them may be of high quality. You can try searching on platforms like Wattpad or Archive of Our Own.
Megan could be a great addition. Her mischievous nature could add a lot of drama and humor to the story. Another good character would be Walter, their dad. He could provide some fatherly advice or get involved in one of their wacky adventures. Also, Crazy Steve from another Nickelodeon show could make an interesting cameo. He could bring his own brand of crazy into the drake and josh world.
First, think about the characters. Recall their personalities from the show. Drake is the cool, music - loving brother, and Josh is the more nerdy and responsible one. Then, come up with a simple plot idea, like a party they throw at their house that goes wrong. Start writing their dialogue as you imagine they would speak in that situation.
