Alternate Rachel Entrypoints into the Series

In case the rumors are true that Rachel Dare will be cut from the Hoover Dam scene, there are two paths I see this show taking to introduce her in S4. (There is no way they can cut her out of the story)

1. The Good(e) Way : They extend the scene at Goode High School where Percy can see the Empousai and he notices that another girl can see them too. Rest of the scene plays out normally with Rachel, the Empousai and Annabeth. Hopefully this is what will happen.

2. The Very, very bad alternate way : Once Percy is marooned on Calypso's island, Hephaestus just...tells Percy that Rachel exists and where to find her. Hera might do this too. While I don't think this will happen, the showrunners are definitely capable of doing this.

What do you think?
