Draco gripped the door knob and they went inside to see Professor Snape standing there with a grayish liquid inside of a vial.

"Po- Harry must drink this if he is to return back to normal" Professor Snape said, and Blaise gently nudged Harry where Snape stood, encouraging him to go to him.

"W-Will it taste bad?" Harry asked, looking at the vial distrustfully, and Snape sighed "Most likely. I do not know how it will taste. It would be better if you pinched your nose when taking it"

Harry nodded, scrunched up his face, and took the vial from Professor Snape, pinching his nose. He took large gulps, wanting to be rid of the vile taste in his mouth. When he was finished, he set the vial down, and looked at Snape expectantly "Is something supposed to happen?" He asked, after a few moments of everyone standing there with baited breaths, waiting to see what would happen, and Snape frowned.

"I don't understand. He should be returning to normal…" Before Snape could finish, Blaise had slammed Professor Snape against the wall, snarling.

"You gave my mate the wrong potion?" He asked dangerously, eyes yellow.

Snape paled, and before he could answer, there was the sound of someone vomiting. They turned to see Harry clutching his stomach, spewing the contents of the potion over the floor. Draco tried to comfort him "What's happening to him?! What did you do to him?! What did you do to my mate?!" Draco demanded, and Snape looked at Harry while he responded "It seems like his body is rejecting the potion I made him. His body saw that something was harmful to his body when it wasn't and wants to get it out of his system. It must've been the dragon hair…" Snape mused thoughtfully, and was brought back to the present when he felt a hand against his throat. He looked to see Blaise glaring at him.

"You had better fix my mate, you old bat, and you better do it now." Blaise snarled, and Snape nodded quickly.

"I will need a sample of his blood while some of the potion is in there so I can find an antidote" Snape said, and Blaise looked at him distrustfully for suggesting that they harm their mate.

However, taking a look at Harry, his adorable little mate, throwing up, he knew what he had to do.

Blaise let go of Snape, leaving him gasping for air, and went to get a needle. Draco paled at the sight of the needle, and Blaise found this amusing. The Ice Cold Prince of Slytherin was scared of a needle?

Oh, Blaise was definitely going to use this for blackmail later.

Pushing that thought to the back of his mind, Blaise approached his shaking mate while Draco held him, looking at everywhere but the needle coming towards him.

With great care, Blaise took Harry's arm gently and injected the needle in his vein, drawing his mate's precious blood. Blaise looked at the blood slowly filling up the syringe, and had the urge to drink. Surely one little drink wouldn't be harmless…

"Blaise! Now's not the time!" Draco shouted, seeing Blaise's eyes turning red; he was hungry.

Blaise was in a trance; he couldn't hear Draco. Right now, his instincts were the only thoughts going through his mind, controlling his body.

'Mate. Blood. Hunger. Claim. Blood'

Blaise sped forward at lightening speed towards Harry, and fangs grew from his mouth. He bit into Harry's neck, and drank greedily, moaning as the feel of his mate's magic ran in his veins. Blaise was suddenly thrown backwards by a furious Draco, eyes yellow.

"You've harmed our mate!" Draco snarled, and Blaise noticed that while he was drinking, Harry had stopped shaking. Actually, he ceased movement all together. Cold fear clenched in his stomach as he thought of the worst.

He looked behind Draco, who was in front of him, to see Harry, his precious mate, unconscious, blood dripping from the bite mark that Blaise gave him.

"You took too much from him. You lost control" Draco stated with authority in his voice, and Blaise dropped his head in submission.

"I'm sorry, Dominant"

"It will be a while for me to trust you again with our mate, but you are forgiven" Draco said, turning his back to Blaise while going to Harry, licking at the wound on his neck, trying to heal it.

When Draco was done, he looked back only to see the mark still there. He frowned.

"Professor Snape, why didn't my vampire side heal my mate?" Draco asked the Potions Professor, who was writing down notes, coming up with a cure for Harry, not daring to interfere between the two creatures lest he lose his life.

He looked up, then to Harry, and the bite mark on his neck. He nodded thoughtfully.

"It seems that Blaise had bit in the exact spot where he was supposed to claim Potter when he was older. With the heat that Potter will be experiencing when he's normal… I believe that your Veela side attempted to claim him before anyone else did, preferring to have his mark visible to all on his skin, marking him as dominant" Professor Snape answered, and Draco looked at Blaise furiously, and Blaise shrunk at his glare while Draco slammed him up against the wall, a feral snarl escaping his lips.

"I am dominant. You are submissive to me. The only person who you are dominant to is our mate. Next time you presume something like this, you will be punished for challenging my authority." Draco snarled out, eyes yellow, and Blaise whimpered, baring his neck in submission, trying to calm his dominant. Draco looked at him distastefully, and Blaise hated seeing that look directed to him. In order to try to calm his dominant, he slowly inched forward to his neck, a soft whine erupting from his throat, and gave his neck a short lick. An apology.

Draco growled his approval, and smashed his lips onto Blaise's.

Blaise grinned into the kiss.

Apology accepted.
