There probably is. Fanfic writers like to experiment with different character interactions. Since both Harry Potter and Cedric Diggory are popular characters, it's not uncommon for someone to write a story where they share a kiss. It could be part of a story that delves into a different timeline, or a story where their relationship takes an unexpected turn due to some magical event or misunderstanding.
One possible plot could be that in an alternate version of the Triwizard Tournament, Harry and Cedric form a closer bond during the tasks. They start to understand each other on a deeper level and as a result, share a kiss as a sign of mutual respect and new - found friendship. Maybe they work together to overcome a greater threat that wasn't in the original tournament, and this shared experience brings them closer.
There's a fanfiction called 'Cedric's Unfinished Story'. In this one, it explores what could have happened if Cedric had survived the Triwizard Tournament. It's really interesting as it weaves new adventures for Cedric, involving him in the fight against Voldemort in a different way.
Well, in some fanfictions, Cedric might use his magical skills to shield Harry from physical attacks. For example, he could cast protective spells like Protego Maxima to create a strong shield around Harry when they are in danger. Maybe in a situation where dark wizards are attacking, Cedric steps in front of Harry and uses his wand to fend off the spells aimed at Harry.
One great 'Harry Potter and Cedric Diggory' fanfiction is 'The Cedric Diggory Chronicles'. It delves deep into Cedric's life before the Triwizard Tournament. It shows his relationships with his friends and family, and how he prepared for the challenges at Hogwarts. It gives a more in - depth look at his character, making him more than just a tragic figure in the original story.
One common theme is redemption. Fanfiction often gives Cedric a chance to redeem himself or to show his true heroism in different situations. Another theme is friendship, exploring his relationships with Harry and other characters in more depth.
It could refer to a plot element where kisses are somehow cursed in the fan - created Harry Potter story. Maybe a character is cursed through a kiss or kisses are used as a vehicle for a dark spell.
The obvious antagonists would be the Death Eaters. They are Voldemort's followers and are often causing trouble in the wizarding world. In this fanfiction, they might be the ones who have put Cedric in danger, either to lure Harry or for some other dark purpose.
The fanfiction could show that Harry discovers a secret passage that leads to where Cedric is held captive. He has to face various magical traps and challenges on the way. Once he reaches Cedric, he uses his Gryffindor courage and his knowledge of magic, like the Shield Charm to protect Cedric from incoming spells, and then they escape together, with Harry being the hero who saves Cedric.
