EDI tells Joker to hook her core into the ship controls, giving her total control of the ship. Joker mumbles about how dumb he is plugging an advanced AI into a deadly warship.
Joker: "This is all Joker's fault, what a tool he was! I have to spend all day computing pi because he plugged in the overlord."
Joker gets everything plugged in so EDI has control of the defensive systems. EDI then asks him to go down to maintenance.
Joker: Arrrgh! You want me to go crawling through the ducts again!?
EDI: I enjoy the sight of humans on their knees.
