"Alright... I need to aerate this place. Make it a little calmer for Draco."
Remus gave him a look. "You really care about him, don't you?"
"When someone puts their absolute faith in you, it tends to make you just as loyal," he responded, eyeing the cage, again.
Remus was quiet for a bit, and Harry could feel his eyes on him. "I'll support you, Harry. In whatever happens. Please be careful, though," he finished, stepped out the door and Apparated away.
Harry wasn't sure what that meant, but he spelled the air clean and washed the floors, walls and ceiling clean and lemon-scented. He left and did the same outside, just in case. Then he Apparated to the front step. 
He opened the door, walked in and yelled, "Draco! I'm going to the shower, okay?"
He was just considering that he should have aerated himself, too, when he made it to the bottom of the stairs. Draco was in the den and practically ran at him. Draco pressed him into the wall, pinning both of his hands to the wall at shoulder level. Harry didn't fight him, though he winced, surprised by the sudden attack.
"Draco?" he said, looking at Draco's pupil-blown eyes right in front of him.
Draco leaned in and put his nose straight into his neck. Harry's head was pushed back to the side and his neck was open. He could feel Draco's teeth just against his skin against his carotid artery. He didn't move, knowing that he was extremely vulnerable in this position. 
"Draco?" he said, again.
Draco whined and pressed his body flush into his. Harry was even more uncomfortable. It was sexual... and at the same time, it wasn't. Draco wasn't humping him or anything. Remus's scent must have triggered a panic response, again. Intentionally or not, Draco had complete control over him now, and his arms were trapped so he couldn't rub his neck to calm him down. Nor could he overpower the werewolf. The week of meals and nutrient potions had given Draco much of his strength back.
"Come on... it's okay? It's Harry, remember? Draco?" he tried.
Nothing. Draco just kept on smelling his throat. Several minutes passed of him trying to reach Draco, but there was no response from his werewolf. Harry let him find comfort in his smell until he felt Draco's lips on his neck. He had to stop Draco from initiating that kind of... stuff.
"Draco! Release my hands, now!" Harry growled.
The anger helped. Draco let go of him immediately and backed into the banister of the stairs. He looked confused, scared and then horrified.
"I-I... what happened? Did I-Harry?" he mumbled, shaking. His eyes were wide and full of fear, and Harry wasn't sure whether in response to his anger or what Draco had just done. He was panicking.
Harry held up his hands. "Draco... calm down...."
That did not work as Draco dropped to his hands and knees and cried, "I'm sorry! I'm sorry master!"
"Stop calling me that!" he spat, but regretted it instantly, as Draco cringed lower to the floor. "Draco, I'm sorry. It's okay. Please get up."
"I don't know what's happening to me!" he cried, and as he wrapped his arms around his knees and began rocking back and forth.
Harry cast the Aerate Spell and then sat down on the floor next to him. Then Harry slowly pulled Draco into his lap to his chest. Draco curled into him, his fingers grabbed his shirt, and then he pressed his face into his chest and cried.
"It's the full moon... everything changes. The healer said that you'd get... different." Her exact words were "sexually active", which Harry did not want to use. "I'm sorry. I forgot to remove the scent from me... so it's my fault. Just breathe."
