2. Marla’s secret phaser changes the hunt
During "Magical Thinking," Ursula joins Marla in the jungle because the colony needs a live Ceti eel specimen. Marla brings the Starfleet phaser she snuck off the USS Enterprise, sets it to stun, then collects a live eel.
Marla then asks Ursula not to tell Khan that she has the phaser, which becomes a monumental turning point between the historian and the Augment doctor. Ursula agrees, treating it as a matter of trust between herself and Marla.
That choice would add real tension to a TV adaptation. The phaser is practical protection, but it also represents the Starfleet values Marla has not left behind. She has been taught not to introduce advanced technology to societies that have not developed it themselves, while Khan has seen any secret kept from him in the past as a challenge to his authority.
The disagreement matters even more after Marla uses the weapon against the Ceti eel queen. Khan is grateful that she saves the group later in the episode, but he still wants to know why she withheld such a powerful tool. Their conversation shifts from the phaser to a larger question: whose values will define the world their child grows up in?
