If you believe, you'll see in time Characters: Padma, Barty Summary: Padma gives a statement to the Aurors, then stops by to see Barty.
"Ms. Patil," the Auror said, rubbing his forehead. "Barty Crouch Jr. is a known Death Eater."
"And I'm telling you that he saved my life in the final battle," Padma said. She crossed her arms. "Plus, as I said previously, I believe he was either possessed or had some sort of split personality. We can hardly blame him if an evil soul took over his body. He was begging me for help, and in the end, the good part of him won and he saved my life."
The Auror sighed, but he dutifully wrote everything down and promised Padma that it would go in Barty's file. He stood to escort her out, but Padma stopped him.
"I'd like to visit Barty, please."
The Auror looked startled. "He doesn't get any visitors."
"Is he allowed visitors?" Padma asked.
"Well, there's no restriction against it," the Auror said, looking doubtful.
"Then I'd like to visit him."
It took some more arguing, but finally the Auror led her to Barty's cell.
"I'll go inside, thank you," Padma said.
This time the Auror didn't even bother to argue, just let her in after she secured her wand in the warded box outside the cell. She really didn't think Barty would try to steal her wand and escape, but she'd won two arguments. She had no real problem following this rule. The door clanged shut behind her, and Padma smiled at Barty.
