If you listen to the first 2 quotes of Cortana carefully, you'll notice a VERY deep voice under Cortana's. This would support that Gravemind is manipulating Cortana. (also the line "i have defied gods and demons" supports this since forerunners were known gods and also demons, and Gravemind is one of very few highly intellegent flood, something like that)
