The reason we should be so very worried about Eve is because she not only physically hurt Villanelle, she emotionally wounded her as well. Although we’ve watched the hitwoman manipulate others for eight episodes, her apartment conversation with Eve seems to be the first time Villanelle has been fully honest with another person. For once, she’s not trying to trick anyone into getting close enough to murder. After all, Villanelle goes to great pains to prove she’s really not going to kill the woman who has been pursuing her for weeks and moves gingerly around Eve, just so she doesn’t get spooked and flee. That is real vulnerability. Then, Eve has to go and stab her in the intestine. For a cold-blooded killer, to quote Villanelle, that hurts — likely more than it would hurt anyone else.
