AW needs more stories. Now Trevor is my favorite (I'm mean Drew Fuller is AMAZING!) so my ideas will either have something to do with him, or be centered on him.
1) Does Trevor's real dad know anything about him, what if he somehow found out he was in the Army? What would he think?
2) Trevor decides to go see his real father before deployment.
3) What was Trevor's dad thinking when he dropped him off at social services.
4) What was Trevor's life like in foster care, and how did it change when he was adopted.
5) What do Trevor's adoptive parents think of everything.
6) How did Trevor decide to join the amry.
7) What if when Trevor was 16 he and his girlfriend (not Roxy) had a baby.
8) Crossover with Charmed. Chris left home after High School, changed his name and joined the Army. (Wyatt is not evil, its Changed Future, Piper is alive there is still Magic.) A demon (for some reason you decide) attacks Fort Marshall and Trevor/Chris has to expose magic. Eventually everyone from San Fran and AW meet.
9)Another Charmed crossover. Everyone from Charmed comes to South Carolina to find Chris (he changed his name like above) they don't know he's in the Army, just that he lives in SC they go into the Hump Bar and meet Roxy and everyone, but he's already deployed to Afghanastan.
