Waiting in a tiny diner for your boyfriend can be more interesting than it sounds. Malec and Solangelo. Kind of a prequel to United(although I haven't gotten to that point in that story yet), but more of just something that totally could happen in these fandoms.

How will this work out?

TMI/PJO/HP/Divergent crossover. Similar to Fandoms In Preschool./ Jace: I'll have…*smirks* Desert. Are you on the menu, baby? Clary: JONATHAN LIGHTWOOD! *Screams* Alec: I'm sorry, ignore him.

Nico is hated and hated by the Camps, and Percy doesn't love him the way he wants. Alec just broke up with Magnus, and is heart broken. This isn't just a story of romance, I mean, how boring is that, but a story of badasssness.
