At first I was all like "Holy shit Cortana!"
And then I realized that was silly. And then I remembered my Halo canon. And then I was all "Holy shit Dr. Hasley!"

And yeah, I paused the video when I thought I saw Capt. Keyes, too. It would suck if the Captain didn't make it into Reach; we know he was there, and he was one of my all-time favorite characters.
