His face earns trust. A hidden picture tells another story.
Let a character keep their public reputation while private evidence makes it harder to ignore what they have done.
Make a science-fiction power feel strange and usable by tracing what it changes about everyday perception and movement.
The first shared trial, the excursion, the dog incident, the heat and return to ordinary speed, and the narrator's later use of the drug.
Professor Gibberne wants to develop a drug that speeds up the whole person, including thought and movement. Its effect greatly exceeds his initial ambition. He invites his neighbour, the narrator, to try it with him. The narrator is nervous but curious and reluctant to appear afraid. Both men experience themselves as moving normally while the surrounding world seems almost motionless.
Gibberne releases a glass, which appears suspended because it is falling so slowly relative to them; he takes it by the bottom and carefully sets it down. Outside, they can study people caught in the middle of a smile or a wink. Music becomes a low, prolonged noise. Their apparent freedom tempts Gibberne to seize a neighbour's irritating dog. Rapid movement heats their clothes, and the narrator attributes this to friction with the air. As the drug wears off, familiar movement and sound return suddenly, leaving the men conspicuously hot and the displaced dog falling into a crowd. The narrator later describes more controlled indoor use, while the proposed drug with the opposite effect remains a future project.
The world is not literally stopped. Wells gives a fictional account, not a workable scientific model at every scale. The men do not initially know the duration or exact rate of the effect; the narrator's physiological estimates are not measurements. The Retarder and future retail strengths are proposals at the end, not devices demonstrated in the excursion. Keep those distinctions if using the story as a source for rules.

Complete English story checked in Project Gutenberg ebook 11870. Demonstrated effects are separated from the men's estimates and future plans. The story warns about forceful contact; the particular injury and rescue in the application are original.
Introduce one changed relation between the user and the ordinary world, then test it with a small action readers understand. Follow through across sight, sound, touch and movement instead of merely declaring the character powerful. Feeling normal can mislead the user about how forcefully or quickly they act on other people and objects. A useful limitation grows from the same advantage: moving much faster may make contact, heat or coordination harder to manage. The result is a power that creates decisions during a scene, rather than a label that automatically solves it.
In an original rescue scene, a character can move faster but has ordinary lifting strength; sudden contact still injures anyone moving at normal speed. Establish that limit when an attempt to tug a colleague's sleeve tears the fabric and bruises their arm. Later, a lightweight shop sign comes loose above a bystander. One hinge still supports it, and its narrow frame is within reach. Instead of grabbing the bystander, the character cups the frame from below, eases its weight onto their forearms and turns it on the remaining hinge towards the empty wall. The decision is how to use the extra time without a damaging impact. Keep that contact limit consistent in later scenes.
