Let's not forget that earlier, Heather's hit by a car on the freeway trying to get to Dylan before Freddy does. Does that stop her? NO. That is the basic definition of a Mama Bear.
Heather's babysitter, Julie, gets another one. A couple of nurses are attempting to give Heather's son an injection that will help him fall asleep—something that they absolutely do not want to happen considering what franchise this is. Julie clocks one nurse in the face, knocking her clean out of the room, and chases the other one out with a syringe. Of course, Julie still dies not five minutes later. But hey, it was still pretty badass.
