I don't think most readers understand Jo atmosphere in the story. With Jo we as readers will see how he enters this life like how Ian and tj did, it just we're seeing it from Jo perspective only, as he's never entered that life style until now. We will see his morals conflict with his desires and how dangerous he will become one he embraces those desires, his up bringing is very different from Ian and Tj so his reaction will be completely different to what the other two did. His character might actual help out BOTH Ian and tj. The author knows what they're doing and you can sense the darkness foreshadowing the author has given us about Jo and that once he comes to full term he might rival equally. Stop thinking it's green vs red, all these characters are imperfect and flawed.
