So, does this mean we all get to start thinking about how our characters know / relate to each other?

Mmhm, you can definitely do that while composing your first posts

Ages to consider for characters, and yes, I included every character offered up via sheet. Even if they're not in the main cast, I'm treating them as part of the world for that purpose, unless their players ask me not to have them a part of the universe. 

19: Walter 
17: Will, Abbie, Danny, Ruby, Astrid, Lila, Bronwyn 
16: Asélie, Gabi, Jessica, Amy
15: G-Mann 

We can assume that characters have probably had classes with each other, with the exception of Jessica, since she literally just moved into town. The high school is not "huge" also, so we can assume that those that did go to Everbrook High at least saw each other in the hallways, even if they did not have classes with each other. 

To give a sample, here's Will's HS Schedule before quarantine closed the school:  

1st Period: Advanced Placement American Literature 
2nd Period: Computer Science and Business  
3rd Period: Trigonometry 
4th Period: Honors Chemistry
5th Period: Study Hall 
6th Period: Honors US History 
7th Period: Film Studies 

The schedule may be based on some high school courses I know of. 

Since I teach. 

I'm so old.
