Unfinished Characters

I am a huge fan of your books, but one thing just feels wrong, that being the question of what happens to the characters after the book ends. Yes, the overall story is completed, but what happens after that? What happened to the non-clones at Serenity? Were Eli and Randy able to stay in contact? Does Cap stay as student president? So many smaller stories are left unanswered, so I think it would be really cool if you had little references to other books in your books. Some examples are a mix between Faker and Masterminds, you could have the boarding school at the beginning of Faker be McNally Academy, and even have a guy named Randy there. You could also have them go to Poseidon, and notice there is a massive empty space in the wall of the lobby(where the fish tank was). These are just concepts, but I think it would be really cool to just wrap up these characters. 

Thanks,
