No universo, ele acumulou impulso apontando-se para baixo e mergulhando na direção de Claire. Claire é posicionada horizontalmente, então ela supostamente se atrasa, similar a como um pára-quedas iria. Ele tem menos "resistência", então ele vai mais rápido do que ela.
Fora do universo, isso obviamente não faz muito sentido. Mas é uma ocorrência muito comum em filmes de ação e programas de TV, e você deve aplicar um pouco de suspensão da descrença . Veja a página da TVTropes em Velocidade Terminal Variável :
How fast you fall depends on who and what you are.
The wacky world of TV physics seems to postulate, among other factors, that how fast a person or object is pulled towards the ground is a function of how heroic they are, and not the constant acceleration of gravity (9.8 meters/second^2) that the rest of us have to deal with.
For instance, no matter how tall a cliff or building is, should a character or a fragile vase fall off, there will always be enough time for the Hero to leap after them, catch up to them in mid-fall, and rescue them.
This is a gross violation of physics in most cases. One object accelerated by gravity alone cannot pass another such object that was dropped before it. Neither the size of the objects nor the relative virtues of them can change that. Galileo and Newton both famously showed this, and Dave Scott confirmed it much later in a near-perfect vacuum.
Even factoring in wind resistance, you'd need to fall a very long distance (as in thousands of feet while skydiving, not the hundreds of feet out an apartment window) for that effect to be workable in your favor. And you also have to make sure the wind resistance is, in fact, in the rescuer's favor (by, say, falling forward and keeping your arms and legs together as the rescuer while the person in danger is falling flat with their limbs hanging out).
It only gets worse if the falling rescuing hero completes the rescue with help of Building Swing gadgetry like grappling hooks or ropes: in Real Life, a falling person trying that would be more likely to lose the rope than save the person on the other end.
Então, novamente, você está assistindo a um programa sobre um cego que luta contra o crime ouvindo os batimentos cardíacos, então você não deve pensar muito sobre isso.
