Pragmata's ending, explained: What happened to Hugh and Diana?

Pragmata’s ending reveals Eight turning on the cast and ordering IDUS to wipe out life on the moon base, then later on Earth.

While protecting Diana, Hugh is infected by the dead filament, hides his condition, and gets her to safety before admitting he is dying.

With no cure available in time, Hugh accepts his fate and chooses Diana’s future over his own survival.

The ending lands as a bittersweet payoff, confirming that Hugh and Diana’s bond is defined by sacrifice rather than a happy rescue.
