Reiner did die in the manga. His death was a result of a series of events and conflicts that had been building up throughout the storyline. It had a major impact on the plot and the other characters.
Mrs Black could be so offended that she starts to plot against Hermione. For example, she might try to get Hermione into trouble with the Hogwarts authorities by spreading false rumors about her.
Harry might become more determined to prove Snape wrong. He's a stubborn character, and Snape's yelling could fuel his desire to show that he's not the misbehaving student Snape seems to think he is.
Yes, there are quite a few. You can start by looking on popular fanfic platforms like Archive of Our Own. There, you might find some well - written stories about Reiner and Mikasa. Some focus on their complex relationship considering their different allegiances in the original story, which makes for really interesting reading.
Once upon a time, in an old, abandoned mansion on the outskirts of a small town, there lived a dark presence. People said that late at night, you could see a figure in the attic window. A young girl, curious about the rumors, decided to explore the mansion one night. As she entered the dusty hallways, she heard strange whispers. The further she went, the colder it got. Suddenly, a cold hand grabbed her ankle. She screamed but no one could hear her. She was never seen again.
There was a dark forest where no one dared to go at night. Legend had it that a witch lived deep within. One day, a group of hikers got lost and ended up in that forest. As night fell, they started to hear strange noises. Branches were snapping as if something large was moving. Then, they saw a pair of glowing eyes in the bushes. One of the hikers shone a flashlight, and for a brief moment, they saw a hideous face with long fangs and matted hair. They ran blindly through the forest, not knowing if they would ever find their way out.
If Lord Reiner is from a particular book or game, more context is needed. For example, if it's a character from a fantasy novel, we would need to know the plot of the novel, the world it is set in, and his relationships with other characters to tell his full story.
