How Does Sirius Black Interact with the Whomping Willow in Fanfiction?

In some fanfictions, the Whomping Willow might be a sentient being that has a special connection with Sirius Black. Maybe it was enchanted by a powerful wizard long ago, and only Sirius, with his unique magical aura, can communicate with it. This could lead to a plot where Sirius enlists the help of the Whomping Willow to defeat a common enemy, like a group of dark wizards who are after Hogwarts.

Another aspect could be the relationship between the Whomping Willow and the characters we know. For instance, perhaps Fred and George Weasley once tried to prank the tree and had a hilarious yet dangerous encounter. Or Hermione might study the tree in her quest for knowledge, trying to find out more about its magical properties and how it fits into the overall ecosystem of Hogwarts.

She could play the role of a problem - solver. For instance, if the Whomping Willow is causing trouble in the Hogwarts grounds by attacking students more often than usual, Hermione might step in. She'd study the tree's behavior, look into old Hogwarts records about it, and come up with a solution to calm it down, like a special potion or a modified spell.

They could interact with a sense of newfound peace. Sirius might be the first to approach Regulus with open arms, ready to forgive all the past. And Regulus would be a bit more reserved at first but then slowly warm up. They might sit together in a beautiful, otherworldly garden and just talk for hours, catching up on everything that happened since they were last together.

They might use the car as a means of escape. Sirius could be driving the car while Hermione casts protective spells around it to keep them safe from pursuers.

One common theme is danger. The Whomping Willow is a dangerous entity in the Harry Potter world, so many fanfictions play on that. Writers might create scenarios where characters are in peril because of the tree's violent movements.

One interesting story could be where Hermione discovers a hidden passage near the Whomping Willow. She uses her intelligence to figure out how to get past the tree's violent branches without getting hurt. Maybe she uses a spell she's been researching in secret.

There are also fanfictions where they are magically bonded in some way. This bond makes them feel each other's emotions and forces them to deal with their relationship on a much deeper level. They have to learn to tolerate and eventually accept each other, which leads to a very different kind of relationship compared to what we saw in the original Harry Potter books.

In this fanfiction, perhaps Harry is trying to tame the Whomping Willow. He might be on a mission to protect his friends from the dangerous tree and in the process, forms an unexpected bond with it. He could be using his skills and courage to face the challenges the tree presents.

In some fanfictions, there might be a plot where a student gets trapped under the Whomping Willow during a full moon and has to be rescued by a werewolf, creating a complex and dangerous situation that tests the relationships between different characters in the wizarding world. The Whomping Willow could also be a central part of a mystery, for example, it might be the key to unlocking a secret about Hogwarts' founding or a long - lost treasure. Characters would then have to figure out how to interact with the dangerous tree without getting seriously injured to solve the mystery.
