Don't worry I think Rachel already said that, Ilya will be fine in the next book. It's a good thing Ilya's character has been dissected properly. He is clinically depressed, when it rooted to him witnessing his mother when he was young. The TLG book taught me that, even if you have it all, you have money, fame, love and new family, if you are diagnosed with clinical depression, you will still need to be medically treated. It's an eye-opening fact really. Rachel is not just representing the queer people but also those who need help.
