Heidi had flown into her haze of anger that seemed standard for anyone of irish blood. She had to be pulled off of Goyle by Zacarias, who seemed to come out of no where, but he held her back.
At Goyle's slur against Trace, Heidi struggled against Zacarias' hold, but he kept it. Once the Slytherin boy had gone, he let her go and she brushed him off, still angry. He got the message and excused himself.
Heidi, in a daze, let Tracey guide her onto the train. "I'm fine." she mumbled. "Are you okay?"
Giving a light smile, Heidi nodded and quickly found them an empty cabin.
