Well to be fair they all have plans. In between fighting Hawkman rogues Greta will be murdered, Wells will become a criminal mastermind, Emerson is really Damage however he'll be more destructive and a badguy in this, and Diggle will bounce sometime in the beginning when he discovers his girlfriend back in Star City is preggers. 

Right now they're here to interact with everyone whenever needed. Unless your hero's in college, everyone will go to Kubert High School starting the following day. Everyone's grade level is based on age. Freshman [9th] for 15 years, Sophomore [10th] for 16 years, Junior [11th] for 17 years, and Senior [12th] for 18 years. You can do any 'Slice of Life' sub-plots you want in school. Have classes with teammates or the four others living in the building, find a romantic interest, etc. 

We'll begin tag-team training in the War Room after your first day of school. And then in the same week go up against one of the Hawkman Rogues.
