This post is about S04E01 of Black Mirror, titled USS Callister.

Half way through the episode, it was established that the Christmas update patch was the wormhole that Cole saw when she was looking through the window, and that, by flying through the wormhole, the ship would run into the system firewall, causing the rogue code to be deleted (and thus freeing them from Daly).

When racing to the wormhole, it was mentioned that the wormhole was getting smaller in size, and is the reason why they took the increased chance by flying through the asteroid belt.

Once the crew reached the black hole, the USS Callister successfully made it through, but not Daly. Regardless of this, according to Kabir, Daly's rogue game code still got deleted, and his controls were disabled.

If Daly didn't go through the wormhole and run into the firewall, why did his code still get deleted?
