re: Dexter 7/21

I hope I am not correct but I think this is how it's going to shake out. Dex is Subject 0. All these other subjects are Vogel's projects. She encourages them and hones their skills.

Now she is dying and is having Subject 0 (Dexter)eliminate them. She is also counseling Deb to have her eliminate Dexter once he is finished so that all of her projects are now complete.
