Excuse me while I just throw my Harry Potter based character at you. :D Not entirely sure what the relationship could be, since El only moved to Deercliff four years ago from the other side of the country (she pretty much backpacked cross country to escape a stalker.) But clearly they need to have or build some kind of relationship. If you're interested I mean. El currently works at a bakery (The Honey Doe) and teaches a women's self defense class at the college two nights a week.
I also have Owen Archibald (gibberishfluent) who Dani could possibly know through Sebastian? They're friends through the university and from being Ph.D students at the same time. And I have Olive Oswald (itsybittsy) who's an engineering student, amateur photographer and climber of tall things.
