Toward the end of the first episode of "Halo," Master Chief — the commander of a squad of scientifically enhanced soldiers known as Spartans — is held at rifle point by Kwan, a teenage captive who has just lost everything.
The weapon poses no threat against the high-tech armor protecting the interstellar super soldier. But after turning to face Kwan (Yerin Ha), who is understandably confused and concerned about her safety and future, Master Chief (Pablo Schreiber) takes off his helmet.
It's a moment that's been more than 20 years in the making.
