So these are not my own theories, but ones that I've seen elsewhere.

What if Octavian was the one to close the doors of death, and sacrificing himself to save the others? This theory reminded me of the Harry Potter series, where it seemed like Snape was a horrible person, but in the last couple of chapters JK Rowling just did a 180 on us and revealed that he was not who anyone thought he was. I can see Rick giving Octavian a heart-wrenching backstory explaining why he is the way he is.

I really hope the whole Caleo thing works out, they seem like a great pair. Some people think that Leo will keep his oath with his dying breath (prophecy) by turning immortal (ergo his last mortal breath) and freeing Calypso from her island. But it could also be the other way around, with Calypso turning mortal and taking her final breath as a nymph. I forget how it worked, but someone explained that Calypsos island only kept her trapped there when she was immortal??? Idk, it made sense when they explained it.

Also, does anyone think Echo will make another appearance? Personally I like Caleo better, but still...
