Jane had a rough day. She managed to do a little homework, but not much because she could not concentrate. She also could not keep still, in the full common room, and in her dorm room, and she kept accidentally getting in people's way.
She eventually ended up sitting, with her feet tucked underneath her, doing the most calming sedentary things she could think of. She knit, with her knitting needles and yarn, but she wasn't really knitting anything in particular. She sang to herself, in a whisper, and rocked back and forth.
Shortly after bedtime, Jane quietly got out of bed, got her parchment, ink bottle, and quill, and snuck down to the common room girls' bathroom. She closed the door, glad to finally have the room to herself.
"Can you hear me," she asked, in parseltongue?
"Yes," the voice said back.
"Don't hurt anybody, ever again."
"I only take commands from my master."
"Maybe I'm also an heir of Slytherin."
"Why should that matter? You're not an heir of my master. He has no heirs."
"Your master's not Salazar Slytherin? But, he put you in the chamber."
"No, he didn't. My master did. He got the idea from a legend."
Jane paced back and forth, unable to keep still, for a while. She eventually stopped, sat on a toilet, and wrote the conversation down, and then she got up and resumed moving.
She later wrote down a description of hearing the voices. She then copied the description and conversation.
The next morning, Jane handed Professor Sprout one of the copies of the description and conversation. She did not mention Harry or Hermione because she felt like she shouldn't without their permission, which she could not get. She did not want to risk getting Harry in trouble, especially since people already suspected him. She did not want people to know she was hearing voices, but she couldn't take it anymore.
Jane watched Professor Sprout reading it. "I'm not sure if this really helps us stop it, but hopefully this will lead us somewhere. Thank you for letting us know," she said.
Jane sat down at the Gryffindor table, next to Neville, at breakfast. She handed him the second copy.
Neville put it in his pocket. "I'll read it later," he whispered.
Jane thought that was smart. People would probably be less likely to get suspicious that way.
Professor McGonagall announced that Dumbledore had been suspended, and she was now headmaster. Jane wondered if that would even change anything.
