Ron narrowed his eyes. "Piss off, Potter!"
"Why are you even still here?" Harry asked Ron.
The redhead threw his hands up. "Search me."
"Go home then!" Harry snapped.
"Yeah, maybe I will!" Ron shouted and took several steps toward Harry, who did
not back away.
"Ron, take off the locket!" Hermione begged.
Sirius's fingers twitched around his wand, watching and listening, desperate to put
an end to the boy's childish outburst—even if he only used a Silencing Charm. However,
Hermione and Harry stood between him and Ron, and the boy's temper was unpredictable,
especially with the Horcrux hanging around his neck. Sirius felt that Hermione was right,
but that did nothing to mollify the nervous anger he felt when the redhead glared at both
of his friends with such malice.
Harry stared icily at Ron, both boys ignoring Hermione's pleas for peace. "Just go
home to your family, and let your mum make you a big dinner and wipe your face for you.
That's what you want anyway."
Ron bellowed back at Harry, "What I want is to make sure my family is alive! It's all
right for you, isn't it? With your parents safely out of the way―"
"Uh-oh," Hermione groaned. Before she could act, Sirius grasped Ron's collar and
lifted him high into the air.
Sirius felt his countenance turn dark, reminiscent of his first meeting with the
redhead in the Shrieking Shack as he stared grimly at Ron. "Too far," he said with a
frightening amount of control in his voice.
"Sirius," Hermione pleaded, "put him down."
Harry glared at Ron. "Yeah, put him down so he can leave."
"Fine." Sirius slowly lowered Ron's shaking form back to solid ground, holding his
stare the entire time. Not letting go of the boy's collar, he used his other hand to tear the
locket from Ron's neck and then released him with a shove for good measure.
"You ever speak to either of them like that again, boy, I'll transfigure what's left of you so
no one will even know where to look," he threatened, his tone low and menacing.
Ron, impulsive as usual, responded by drawing his wand.
