Not trying to be nitpicky. I loved the episode. But, she can survive this…
And this…
But getting lightly squeezed around the midsection causes…
I mean…yeah.
Garnet…doesn’t squeeze LIGHTLY
this gem can literally pick up a full sized injector with one hand, I don’t think that Peridot got ‘lightly squeezed’
she practically got cut in half by Garnet
Also, you’re comparing mere rocks to a hard light gem weapon.
being crushed by rocks and injecters spreads out the force over her whole body and evenly distibutes it whereas being squeezed by garnet forces all the force into a tight spot, causing more damage.
