@Zoboso: -Why is it so hard for you to say Semblance right....

-I'm perfectly sure you barely understood that xkcd explanation. It's different here, Ruby is not using her Aura like a gun, she's basically making an horizontal jump. Or in that picture, kinda-diagonal jump.

In normal cases, all she does is move fast. As in, just that, move fast, like the Flash but not necesarily running. So fast the human eye can't see her.

In that specific case, since one can't walk or run in the air, it's like a jump. You are in a wall, you jump from it. As such, you are pushed forward. The force is applied in the contrary direction, hitting the wall that in most cases should be tough enough to resist the force and as such not be moved at all. In simple words, it's recoil what hits the wall, not what moves you.

She used her Semblance while jumping from that wall. Result: A quick diagonal jump. It's not using it like a gun. Reason: In the xkcd example, firing a gun so the recoil pushes it up. The recoil is the force applied in the contrary direction everytime one fires the weapon. But the recoil is not what fires the bullet, it's only a product.

Same here. Ruby jumped from that wall. The jump is like firing a bullet. The force applied is applied backwards to the wall, like recoil on a gun. Only the wall does resist it easily. But like I said, it's not using her Semblance like a gun to move, that would mean she uses the recoil (which would be towards herself) to move, and that is bullshit, not what happens. The recoil doesn't move her, she is the one moving herself.

When she fires CR behind her to move quicker, that's when she does that xkcd example. Got it memorized? When she simply uses her Semblance, it's not that xkcd example. Got it memorized?
