Celeste explains who she is, and why she's here. Celeste is determined to show Hillary that she's safe and sound in the hands of the world's only possible lesbian savior. On top of that, having the one person who's always been there to support you, and make sure you don't feel like a crazy person abducted in order to keep you quiet about your world changing discovery, it's no wonder that Celeste, the world's first and only Artificial Intelligence, shows up to help the poor devastated lesbian stick it to the man.
It's not easy being a lesbian, but to have your life's work, work that's so important to human existence, and the world just yanked out of your soul over the guise of National Security must be devastating.
Hillary has been through what must be the most invasive attack on her person in her entire life.
