"Yes, I've heard all about your treatment methods. I need you to put the jar down and face the wall. You are under arrest," Ron said, his eyes gleaming in rage.
Higgs looked at the potion and then the door. He couldn't vanish it or Apparate away. It was a magic-proof room. Harry froze in anticipation. He wasn't sure what was about to happen, but knew Ron was pissed.
"I am the appointed mind healer for Potter. I can give him anything I deem necessary and prohibit his visitors," Higgs declared, trying to justify his actions.
"I'm not here to visit Harry. I'm here to arrest you. Now, turn around before I make you," Ron  hissed, as he stepped forward, no wand in hand.
"There's no magic here, Weasley," Higgs sneered.
"I know. It will feel so much more satisfying wrestling you to the floor to cuff you, the muggle way," Ron growled, as he pulled out a pair of muggle handcuffs.
Higgs looked nervous and eyed the door, again.
"By all means... flee and resist arrest," he taunted, nearly shaking in pent up rage.
Higgs jumped toward the door, but Ron straight-out tackled him into the wall. Higgs was then forced to the floor, dropping the jar. It clanged noisily on the floor, but didn't break. However, Ron pulled him roughly away from the door by his robes, dragging him across the floor. Higgs struggled, trying to free himself, but Ron dropped on top of him to secure him. They rolled out in front of his bed, where Harry couldn't see due to the restraints. 
There was a fury of thuds and owhs, the sound of fists meeting flesh and Ron growling orders to stay down. Then, Harry heard the distinct clicking of the handcuffs, and Ron finally stood up, his fists bloody and was panting hard. Ron took some deep breaths and looked to be considering beating Higgs more, but decided against it. Ron took a deep breath and started to walk over.
"Harry..." Ron breathed, coming to his side.
Tears of happiness formed in his eyes, and Harry looked at his face, relief flowing through him.
"I'm so sorry, Harry, that I left you like this, but he needed to confess it to me," Ron said, his face lined with sadness.
Harry nodded and mouthed okay. And it was okay. It was better this way. He held up his wrist closest to Ron, in a wordless plea. Ron nodded and went back over to Higgs, searching him, Harry assumed. Ron stood up, screwed on the lid on Higgs's jar and pocketed it, before he came over with the key. He figured out how to use it and released his hand. Harry brought it immediately to his chest as tears formed in his eyes, again.
Ron slowly released his other limbs, and when he was done, Harry curled up into a fetal position, immediately. Ron crotched down in front of him and, thankfully, didn't reach out for him, yet. The tears started to fall, again. He had never felt so weak and vulnerable in his presence before. He wasn't this bad after the trial, or when he was at Luna's. But this was Ron... his brother. He came to save him.
"Easy, mate. Easy, now. I'm here, and he's never going to hurt you, again," Ron whispered.
Harry sniffled into his pillow and just nodded.
"Hermione is dealing with Harding. She might even have the muggle potion for your tongue, but everyone is waiting for my go-head. I want to make sure that you're ready for her and other Aurors."
Harry met his eyes, and his hand reached out for his. Ron clasped it gently, and Harry mouthed a "Thank you."
"No problem. I'd do anything for you, Harry," Ron said, tears coming out of his eyes, too. "Do you think you can stand? I can help you out of here."
