One possible plot could be that Natsu is completely devastated by Lucy's death. He turns to alcohol as a way to numb the pain. His friends might try to reach out to him, but he pushes them away in his grief. He could start having flashbacks of their adventures together while drunk, which makes his pain even more intense.
Well, in such a fanfiction, Natsu might first go into denial about Lucy's death. But as the reality sinks in, he gets drunk. He may end up in a bar frequented by wizards. While drunk, he could get into fights with other wizards who accidentally say something that reminds him of Lucy. His drinking could lead to him losing control of his magic in a dangerous way.
In this fanfiction scenario, Natsu's world shatters when Lucy dies. He starts drinking heavily. As he gets drunk, he might wander around Magnolia aimlessly. He might visit all the places that were special to him and Lucy, like the park where they often sat or the guild hall. His drunken state could also attract the attention of some dark forces that see his vulnerability as an opportunity to attack, but he is so consumed by grief and alcohol that he doesn't notice the danger at first.
