As she doubled over, Heidi went back to leaning on Tracey for support, arm around the other blonde's waist tightening, ignoring Sara for the moment as she tried to keep her blurring vision clear.
Sara laughed when Tracey instantly worried about Heidi as she doubled over. It felt good to see the other girl hurt. Sara had been hurting too, though she would barely admit that to herself, when Heidi had stolen Tracey from her. What she had done to Heidi was just overdue payback.
As Tracey pointed the wand at her, shaking slightly and threatened her, Sara only continued to grin. "Go ahead." she taunted Tracey. "Do it and see what happens." She referenced back to her threat the first time Tracey had threatened her. She could tell Daphne in a second if she had to.
"But honestly," she began, acting nonchalant, even with the wand in her face. "It would hardly take me to tell people. What kind of Slytherin would help a Hufflepuff if they weren't getting something in return. And I'm sure people could figure out just what that something is."
Heidi managed to sneer from her state, being supported by Tracey. She quickly understood that Sara was threatening to out them, nothing that she would have a problem with, but knew Tracey would. "You should mind your own business, Moon."
"Oh and what are you going to do, Macavoy, you'd probably thank me for outing you two."
Heidi only stayed silent as she glared at Sara. She moved to stand on her own again when she felt the pain again and went back to leaning on Tracey. "Let's just go, Trace." she mumbled so only Tracey could hear.
