The Halo TV show blew through all its best lore in the season 2 finale, and it was kind of worth it

Halo’s second season ends with the strangest episode the show has ever had. Unlike the rest of the series, which has slow-played every single one of its reveals, carefully rationing them out a crumb or two at a time, the season 2 finale threw just about every major reveal from the first Halo game at viewers in the span of less than an hour. Consequently, it was also probably the most interesting episode the show’s ever had, particularly for longtime fans of the game series.

[Ed. note: This story contains spoilers for Halo season 2.]

The episode opens with the audience following a character we don’t really know. She’s a scientist and clearly acting funny, but things don’t get really strange until the bizarre music — unlike anything heard in the series so far — kicks in and we see the scientist slowly start to lose her mind, spontaneously staring off into space or twitching wildly before stabbing a coworker. It’s strange and unsettling, but it’s also the most clever bit of fanservice the show has pulled so far, as the tumbling realization that the Flood are about to make their first appearance on this show slowly dawns.

For most of this show’s first two seasons, the Flood seemed like a bridge too far for the tone it was taking. The most destructive aliens in Halo’s canon, the Flood are a parasitic race that seeks to consume and assimilate every living thing in the galaxy, infecting them then taking them over as newly zombified hosts. Their appearance in the original Halo marks one of the best and most unexpected twists in video game history, and frankly the show did an admirable job of mimicking it, even under far different circumstances.

The Flood of the Halo TV show are a little bit more like traditional zombies than the games’ version. But to showrunner David Wiener’s credit, the series doesn’t skimp away on their gross creepiness. The larger zombified human forms sprout extra limbs, sprinting toward potential new hosts while wildly flailing their alien appendages. Soren and Kwan are left to shoot their way through the hordes of the undead in a surprisingly fun firefight. But even better is the fact that this scene ends with another of the finale’s interesting reveals: the visions Kwan has seen throughout the season are actually of someone trying to convert her into a willing assistant of the Flood.

The original Halo canon doesn’t really have an analogue to this, especially not on the human side of things, but it’s a fantastic and fascinating addition if the show has the guts to see it through. The Flood’s entire purpose is to end all organic life, which would basically make its human followers a death cult dedicated to bringing about the end of the universe, adding all life to the Flood collective hive mind — which is a both terrifying and cool idea for the show to explore. The Halo TV series has always seemed reticent about (and almost embarrassed by) the game series’ strangest lore, and it doesn’t get much stranger than the Flood. So for the series to dedicate time to exploring a religion that worships an ancient race of exterminators would be a fascinating step in the right direction, and a perfect counterpoint to the Forerunners and their Halos, which were once used as the ultimate anti-Flood weapon.

It should be telling that this is also the first episode of the Halo TV show where Master Chief sets foot on the titular ring and it only merits bringing up now. It’s hard to be particularly invested in his plot there when his reason for being there was so deeply tied to both Makee and the UNSC’s convoluted plotting this season. But it’s undeniably nice to see the familiar Forerunner architecture of the Halo ring rendered so well in the episode.

And just like the strong parts of the rest of this finale, the most interesting thing about Chief’s time on the ring is also Flood related. The season ends by revealing that Master Chief and Makee have both been spending time being interrogated by 343 Guilty Spark, the monitor of this particular Halo ring and long considered the most hated character in Halo history — mostly because he’s not particularly trustworthy and guides you through one of the first game’s worst levels. He’s also the first real representative of the Forerunners that players get in the games, and it’s fun to have him play a similar role in the show.

After 17 frequently grueling episodes, Halo finally feels like Halo by the end of its second season. It doesn’t excuse the fact that the road here was paved with boring subplots, frustrating characters, and bad writing. Remembering how watching all that build up felt certainly makes it hard to have optimism for what this show could be if it returns for a third season, even if it’s now in the best place it’s ever been. But hey, at least for fans of the games, the show finally looks and feels a little more recognizable now.
