Another motive could be information retrieval. As Lupin is often part of the Order of the Phoenix or has connections to important wizarding figures, other parties may think he has valuable secrets. So, they kidnap him to try and force him to disclose that information.
A possible motive could be revenge. Some characters who have a grudge against Lupin, perhaps because of his association with certain groups or events in the wizarding world, might kidnap him. For example, if a werewolf-hating group found out his identity, they could kidnap him to make an example out of him.
It could also be a case of mistaken identity. Maybe there's another wizard who looks a bit like Lupin or has a similar name. Dark wizards might kidnap him thinking he's someone else who has something they want, like a powerful magical artifact or a key to a hidden magical place.
One possible plotline could be that Hermione starts flirting with Remus as a way to learn more about the wizarding world's history from his perspective. Since he's older and has experienced a lot, her flirting is a means to an end at first, but then it develops into something more.
One possible motive could be ransom. The kidnappers may think the girl's family is wealthy and they can get a large sum of money in exchange for her safe return.
Love or obsession could be a motive. Just like in some stories where a girl is so in love with a boy that she kidnaps him thinking it's a way to keep him close.
One possible motive could be Bellatrix's loyalty to Voldemort. She might think that by kidnapping Hermione, she can get information about Harry Potter and the Order of the Phoenix. Hermione is known to be very intelligent and Bellatrix could believe she has valuable knowledge. For example, Hermione might know the location of Potter or the Order's plans against Voldemort.
One possible motive could be to use Hermione as a bargaining chip against Harry Potter. Since Hermione is his close friend, the kidnappers might think they can force Harry to do something, like give up a powerful magical item or valuable information.
There's also a fanfic called 'Remus and His Soulmate'. It's a shorter piece but still very engaging. It focuses on the small, everyday moments between the reader and Remus. These simple interactions show how strong their soulmate connection is, and it's a really sweet read for any Remus Lupin fan.
One possible motive could be a deranged fan's obsession. In some fanfiction, a fan who is overly obsessed with Seungri might kidnap him out of a warped sense of love or possession. Another motive could be related to a rival in the entertainment industry trying to get back at him or the group. They might think that by kidnapping Seungri, they can disrupt Big Bang's activities and damage their reputation.
One possible motive could be to use Miko as a bargaining chip. Maybe the kidnappers want to exchange her for some valuable object or information within the Transformers' world. For example, they might be after a powerful Energon source or a secret Autobot technology.
One possible motive could be a conflict over their loyalties. Remus is a werewolf and has his own set of insecurities and allegiances. Maybe Snape discovers something about Remus that he threatens to expose, leading Remus to kill him in a moment of panic. For example, if Snape were to find out about Remus endangering students during his werewolf transformations and was about to report him to the authorities.
Well, one possible motive could be that the kidnapper is a villain who wants to use Nico as a bargaining chip against the other demigods. Maybe they want to trade him for some powerful artifact or to gain access to the Underworld. Another motive could be that the kidnapper has a personal vendetta against Nico or his family.
