In a 'Juvia Gets Drunk' fanfiction, Juvia would most likely interact with the members of Fairy Tail. She might start bothering Natsu, asking him silly questions like if he can really breathe fire while drunk. She could also interact with Happy, and they might get into some sort of funny exchange, like Juvia trying to teach Happy a new song she made up in her drunken state. And of course, she'll interact with Cana. Cana being the drinker she is, might find Juvia's drunk behavior either hilarious or relatable and they could have a long chat about different kinds of drinks.
Their relationship would likely become more serious. They would have to think about not just themselves but also their baby. There would be more commitment and responsibility between them.
Gray could be a great addition. Since Gray has a history with both Juvia and Lyon, his presence can add a lot of drama. For instance, his reaction to Juvia and Lyon getting closer could range from jealousy to acceptance, which would create different story arcs.

One idea could be a story where Natsu and Juvia team up for a mission. They initially clash because of their different personalities, Natsu being hot - headed and Juvia being more reserved and love - stricken for Gray. But as the mission progresses, they start to understand and respect each other's strengths, and form a strong friendship. For example, Natsu could learn about Juvia's water magic and how she can use it in creative ways, and Juvia could be impressed by Natsu's determination and never - give - up attitude.
