Heidi only kept her stance and glared at Goyle, not really caring about the name calling, but still upset that he had hurt Tracey. No one hurt Tracey on her watch.
As the fat boy called to his friends, Heidi clenched her fists, ready for a fight if need be. Hearing him call Tracey a slag was the last straw. She grabbed him by the collar and held him firmly. "Don't you dare call her that, you bloody prat."
Feeling Tracey's hand on her arm, Heidi didn't take her eyes from Goyle. "No one calls you that, Trace." she told her girlfriend.
