I NEED AN ANSWER QUICK
WHAT HAPPENED IN THIS SCENE?

(Vanessa, who usually acts tough, has a splinter and approaches Emily)
Vanessa: I have a splinter. Can you take it out?
(Emily grabs Vanessa's finger and begins moving the splinter)
Vanessa: Ow.

My question is why did Vanessa say "ow" even though she usually acts tough and could've kept it to herself.
