Joel: Emily is shown to be one of the few people that was ever caring towards Joel. She doesn't become intimidated by his fierce personality or appearance. It's shown he feels the same way about her, as they both defend each other when captured by the CRU. Joel even goes as far as to open up about his personal life with her.
Paelen the Magnificent: She mistakes him for a human boy at first, oblivious to the fact that he was an Olympian. It's later shown that Paelen cares deeply for Emily, admiring her bravery since she is just a mere mortal human.
Diana: Another Olympian. Emily thinks of her as a friend. She's also seen alongside Emily in her journey, providing strength to the group.
Pegasus: She is shown to have a strong emotional connection with Pegasus. She seems to understand him, despite the fact that he cannot speak her language. She also admits to being "jealous" that someone else could possibly take her place in his heart. At first she's scared, and of course fascinated by him. Just like Joel, she and Pegasus protect each other throughout the entire story.
