lost halo 4 vid? help me out here please

so, there is a vid where cortana reviews human history and isn’t sure if she wants to wake him up. I cant find it anywhere. does anyone know what it is called or where I can find it? I think it was part of forward unto dawn but it got cut for some reason. in the vid cortana leans against the lid of the cryo tube and tries to talk to him. anyone?

I might be mistaken but i believe that is Halo Origins.
