Harry honestly didn't know how this happened, one minute he was trekking through the dungeons to get to the potions classroom for his detention with Snape – on the second bloody day back – he had been rounding a corner when he heard something up ahead that made him speed up in time to catch three Ravenclaws surrounding a scarily familiar blonde as they tugged his trousers off. After that it was pretty much a blur, he had known straight away what they were doing, an idiot couldn't have mistaken the fact that Draco definitely wasn't willing if the sobbing was anything to go by, then a rush of anger had washed over Harry and before he knew it he stepped forwards and was firing borderline dark hexes at the three boys before going to Draco and throwing his robes around the naked boy and tugging him into his lap, cooing and rocking him as he carried on crying for Merlin knows how long until Snape came around the corner, clearly intent on hunting Harry down when he hadn't shown up for his detention. Which led them to the position they were in now. Snape was trying to get Draco off Harry, Harry was honest to Merlin growling at the man and holding tightly onto the blonde who in turn was clinging to him while three boys bled heavily and unconsciously on the ground around them.
"Potter give me Draco now!" Severus snapped.
"Piss off!" Harry snarled back shifting and actually biting Severus when he tried to take Draco. Yelping Severus jumped back and stared at Harry assessingly.
"You clearly aren't his mate or you would have killed them and claimed him by now, so why are you so protective of him?" Severus sighed rubbing the bridge of his nose. Frowning Harry glanced at the man.
"Mate?" he asked.
"Draco is a submissive veela. But you aren't his mate otherwise you wouldn't be acting like this...that doesn't explain why you are acting like this...or why he is accepting comfort off you as he should only be comfortable with his..." Severus cut himself off staring wide eyed at Harry.
"With his what? Damn it Snape, with his what?" Harry pushed when the man just gawped at him.
"Come with me Potter we need to discuss this somewhere private...and get Draco somewhere safe," Severus added. Harry scowled when the argument died on his lips at the addition knowing Snape had done it on purpose. Sighing he cast a feather light charm on Draco before standing and carrying him through the dungeons and up through the school to the fourth floor after Severus until they reached a portrait of a severe looking man. Severus whispered the password before motioning for Harry to follow into what Harry quickly deduced was Severus's living quarters. Slightly stunned that the man would allow him within three hundred yards of his living quarters never mind inside them Harry turned to look at Severus questioningly.
"What's going on?" He asked cautiously.
"Sit down Potter you might as well make yourself comfy," Severus sighed pouring two glasses of firewhiskey from his decanter while Harry cautiously sat down on the sofa, a hiccup from Draco had Harry's attention back on him and he arranged the blonde comfortably on his lap cooing and stroking the blonde hair again while Draco snuggled closer. When he looked up Severus was watching with mild horror and wonder but upon realising he had Harry's attention he handed him one of the glasses and took the other with him as he sat down in the armchair.
"Professor...please what's going on?" Harry asked again sounding slightly desperate.
"Potter have you had Defence yet?" Severus asked.
"No why?" Harry frowned at the seemingly off sequence question.
"Perhaps it is for the best then, I need to get Lucius in here to explain. I'll be a second," Severus sounded so tired that Harry didn't argue as the man hurried out the rooms, instead he focussed on trying not to wake Draco as he combed his fingers through the light blonde hair. He didn't know where these protective, caring feelings for the blonde had come from but he wasn't fighting them when the teen clearly needed comfort after what had happened. If Harry had been a few minutes later it would have been too late to help him...the thought made Harry want to throw up. His thoughts were distracted when a grumbling Lucius Malfoy walked in following Severus, his grumbling stopped at the sight in front of him though.
