I feel like Reyna might die at some point. Rick has developed in us enough of an emotional attachment towards her to feel sad if she dies, but not enough to make her "un-killable" like Percy, Annabeth, Tyson, and Grover are. He has also stressed that she is all alone and depressed. I think she will either find someone or be killed off.
