In HP fanfiction, 'Alls fair in love and war' might imply that in the context of relationships (love) and conflicts (war) within the Harry Potter universe, characters may use any means necessary. For example, in a romantic sub - plot, a character might be a bit sneaky to win the heart of another, just as in war - like battles against dark wizards, some might bend the rules to gain an advantage.
In some HP fanfiction, in the love aspect, it's shown as characters lying about their feelings or identities to get closer to the one they love. In war, they might steal potions or spells from the enemy. For example, a character could pretend to be on the side of the Death Eaters to get information. In other stories, it could be more about using emotional manipulation in love and using unforgivable curses in war.
Well, it could be about the idea that in the context of a love - themed fanfic, different actions or behaviors that might not be acceptable in real - life relationships are considered fair in the fictional world of the story. For example, characters might engage in some sort of competitive pursuit of love in ways that are a bit unorthodox.
Naruto's abilities would be quite formidable in the Holy Grail War fanfic. His speed and strength, enhanced by his ninja training, would give him an edge. His jutsus like the Summoning Jutsu could bring in powerful allies. However, he'd need to be careful as some Servants might have abilities to counter his attacks.
Sorry, I haven't actually read this specific fanfic, so I can't give exact examples. But it could be things like a character lying about their identity to get closer to the person they love. In normal life, that's not cool, but in the fanfic world, it might be part of the plot.
One of the morals could be about the importance of self - acceptance. In the story, the main character goes through various challenges in middle school, and as she learns to accept herself, she starts to grow and face difficulties better.
It's about how the final outcome can overshadow the problems and troubles in the journey. In 'Alls well that ends well story', it shows that the end state of affairs determines how we view the whole sequence of events. If the ending is positive, like in the story where the characters get what they desire in the end, then all the prior chaos and confusion can be seen in a different light.
Helena is one of the main characters. She is a strong - willed woman. Bertram is another important character. Their relationship and the events that unfold around them form a major part of the story.
