Using the old Hobo's yard for Nick's training of the weaker students is a good Idea. The place hasn't been used for anything since Jake hid out there.
Other Non-Cliques that we haven't mentioned much (or at all) in the game include Gordon, Ivan, Trevor, and even Pedro. They could all benefit from Nick's teachings.
Still recovering from injuries are Lance and Ray. I'm going to slot Lance in with the Jocks for his protection. Ray will not be coming back until Chapter 5, and could be trained then. I got plans to fit them both into the storylines then.
