I'll admit, I had a bad feeling about this episode right when the first-look images dropped, featuring a glaring absence of the Master Chief, Dr. Halsey, or anyone else that the overarching storyline of "Halo" has focused on up to this point. Those concerns only increased as early as the "Previously on 'Halo'" segment, which took us all the way back to the opening minutes of the premiere to remind us of the situation taking place on the planet of Madrigal in the aftermath of the Covenant invasion.
