Halo

TheHalo season 2ending has moved Master Chief’s story forward in a serious way. This year has already seen the Fall of Reach, the teasing of The Flood, and Forerunner lore lurking in the background, but the finale to the second season now means we’re into some very familiar territory for fans of the shooter series.

With that exciting development, inevitably, comes questions. Several key players’ fates are up in the air – or, sadly, definitively closed – and there are new alliances, fresh faces, and a seismic change to the show that all needs to be addressed.

And address it we shall. Below, you’ll find a recap of the major events of the Halo season 2 ending, plus all the fallout besides. That includes the identity of whoever was talking to Master Chief at the episode’s end, a deeper dive into the Halo ring itself, and any other burning questions you may have after ‘Halo.’

Spoilers for Halo season 2 follow.

Halo

Away from the action, Miranda Keyes is seen observing the artifact she recovered from Halsey’s old lab. However, she unwittingly spreads the parasitic entity known as The Flood, which turns its hosts into zombie-like feral creatures, complete body horror-style transformations.

Kwan Ha properly meets The Mother for the first time and discovers that she is from a line of protectors who have held off The Flood.

The season ends with the reveal that Master Chief is talking to Guilty Spark, the caretaker of the Halo ring. He warns something is lurking below: “It is awake because you are here, you are here because it is awake,” he declares. “I’ll be watching.”

What are The Flood?

Halo

While we’re reluctant to diptoomuch into the game lore (the Halo TV series exists on a separate ‘Silver Timeline’),Bungie’s original trilogy does offer up a little more info on The Flood. Namely, that they’re a parasitic hivemind whose only aim is to wipe out all sentient life in the universe.

Who was talking to Master Chief?

Halo

That sure looked like Guilty Spark who, in the Halo games, was the AI caretaker of the first Halo ring Master Chief encounters on Installation 04.

We imagine he’ll have a similar role here – accompanying Master Chief through the Forerunner structures as a companion-of-sorts. Be warned, though: he has his own motives, ones which should become apparent sooner than later.

What can the Halo ring do?

As Makee puts it, “everything will be clean” if the Halo ring is activated. “That’s the ring’s purpose. And its power.”

What is Kwan Ha’s role in all this?

Halo

In a break from established Halo canon, it appears Kwan Ha is being positioned as both protector and the key to some unknowable truth surrounding The Flood. The character, an original creation, doesn’t have any basis in the games so it’s tough to predict where it’s going – though we’d wager Kwan Ha will have a more prominent role in future seasons as the galaxy’s savior given how she was effectively sidelined for large parts of Halo season 2.

What next for Halo?

Halo

If a third season does happen, it should broadly follow the same path of Halo: Combat Evolved insomuch as it will be Master Chief up against the Covenant and the Flood to stop the ring being activated.

In the show’s case, Makee will likely be the antagonist once more, with Kwan Ha coming into more significance. Soren and, surprisingly, Ackerson all seem to be on Chief’s side in any upcoming conflict too.
