This is just standard operating procedure for Cortana. She specifically optimized her firmware to download all the latest software updates this way. Cortana wrote this code for all the future ai updates. She came up with the idea watching MASTER 'DADDY' CHIEF showering and the water cascading of his massive White cock hanging like a elephant trunk not even hard, and his huge low hanging tennis ball size ballsack. Her plan was full proof, no way MASTER CHIEF would be suspicious of her actions, as it was by-the-book... although it was every day, sometimes more than once, and in the middle of battles.
But hey the Covenant didn't mind the free show. ^_^
