In fanfiction, the Time - Turner can be a tool to bring Hermione and Snape closer. For example, if Hermione uses it to help Snape with a past event, he may start to trust her more. This newfound trust can change their relationship from one of animosity in the original story to a more collaborative and understanding one. They might share secrets and knowledge that they wouldn't have otherwise.
One plot could be Hermione using the Time - Turner to go back and change Snape's perception of her. Maybe she tries to show him that Gryffindors can be worthy allies. Another could be that Snape discovers Hermione's use of the Time - Turner in a way that wasn't in the original books and they end up working together secretly to stop a new dark threat.
Another plotline might involve Snape discovering Hermione's use of the Time - Turner and initially being suspicious of her motives. But as they interact more in the altered timeline, they end up forming an unlikely alliance. They could work together to uncover a long - buried secret about Hogwarts that was lost in time.
Their relationship would likely start off with a lot of tension. Snape is used to being distrustful of Gryffindors, and Hermione is not one to take Snape's snide remarks lightly. However, as they are forced to interact more due to the Time - Turner situation, they might gradually develop a mutual respect. Hermione would come to understand Snape's complex past, and Snape would see Hermione's intelligence and determination.
Snape would have more opportunities to right his wrongs. For example, he could go back and be more honest with Lily about his feelings. His character could become less bitter as he gets a chance to change things that made him so resentful in the first place.
I'm not sure of the exact title, but in some fanfictions, Hermione using the Time - Turner to save Snape often involves a lot of mystery and intrigue. For example, she might have to solve some puzzles or face some dark magic in the process. Sometimes, she also has to convince other characters to help her in her mission, as saving Snape is not something that everyone would be on board with, considering his complex character and past actions.
One great 'Time Turner Hermione' fanfiction is 'Hermione's Time - Turner Adventure'. It delves into Hermione using the Time Turner for more than just attending classes. The story is full of mystery and her character development is really interesting as she faces new challenges.
Hermione got a Time - Turner in the Harry Potter series. It was a very special device that allowed her to go back in time. This was crucial for her to attend more classes than were physically possible at once. For example, she was able to take both Muggle Studies and Ancient Runes at the same time slot. It also played a significant role in some of the adventures she had with Harry and Ron, like saving Sirius Black and Buckbeak. The Time - Turner was a magical yet dangerous object, as misusing time - traveling magic could have disastrous consequences, but Hermione managed it quite well most of the time.
Well, one plot point is that Hermione often has to keep her mission a secret. If other people, especially those who don't trust Snape, find out what she's doing, it could cause a lot of problems. Also, there's usually a part where she has to face the consequences of changing the timeline. For instance, some relationships might be altered, or new threats might emerge. In some fanfictions, she also has to deal with Snape's initial disbelief or hostility when she tries to save him. He might not trust her motives right away, and she has to prove that she's really there to help.
In fanfiction, Hermione's Time Turner often leads to really interesting plot twists. It allows her to be in two places at once, which creates a whole new set of adventures. For example, she might use it to study more subjects than she could normally, but then get caught in a time - loop where she has to solve a mystery that's causing the loop.
