Hopefully this makes sense.
Disclaimer: Sadly I don't own Harry Potter, it's all JK Rowling's work.
Lucius' companion froze everyone but Narcissa, Draco, Lucius and Harry, (everyone could still see what was going on they just couldn't move) Harry was hidden behind Lucius in a body bind,
"Narcissa, Draco, pack your belongings we are leaving." He commanded
"No Lucius, we aren't" Narcissa said in anger
"You will, or he gets tortured and killed." Lucius stated as he pulled Harry from behind him and placed him in front of himself, Lucius removed the body bind but put a wand to his neck. Draco and Narcissa gasped as they took in his bruised and bloody appearance and then quickly pulled their wands out however they forgot about Lucius' companion who quickly took the wands off them with 'Expelliarmus'
"Now that wasn't a very smart idea Narcissa, you should know better" Lucius said as he pushed Harry to the ground and smirked nastily before quietly although everyone heard it saying
"Crucio" Harry writhed in pain on the floor, he bit his lip hard enough to draw blood to keep himself from screaming out, by the time Lucius stopped the curse lots of blood was dripping down his chin. Lucius looked up at Narcissa expectantly, to which she sighed and looked down at the ground grabbing Draco by the hand they started making their way down from the staff table when Harry suddenly shouted out in a raspy voice
"No Draco, Cissy. Stay where you are." Lucius looked down at Harry with cold hateful eyes before kicking him in the ribs harshly
"Shut up, you filthy half-blood. How dare you speak to my wife and son in such a disgraceful way." He growled
"Father stop! Please." Draco begged his father as he saw the man pull out his wand, Lucius' attention went to Draco as the older man just stared at his son in shock, before they flicked over to Narcissa,
"What have you done to my son Narcissa? He's behaving like a muggle, you have even allowed him to associate with half-bloods and filthy mudbloods" he yelled
"Lucius please leave Harry alone, leave us all alone. I am no longer your wife, I have taken back my family name, I am not a Malfoy I am a Black and Black's don't allow people to control them, you are no exception."
It was the only diversion Harry needed as Lucius and Narcissa spoke, Harry quickly pulled out his wand and cast a silent 'Stupefy' and 'Petrificus Totalus' at Lucius' companion who let out a gasp and then fell to the floor with a thud, Lucius turned around at the sound but was to slow as Harry had already cast the same spells at him.
The students and staff who had been frozen got unfrozen and just stood in shock thinking about what they just witnessed.
Harry suddenly collapsed back to the floor unconscious, Draco ran to him as fast as he could and cradled his head on his lap and in his hands, still looking at Harry he yelled
"Someone help me get him to the hospital wing" Ron ran over quickly and the two carried him to the wing and as soon as Madam Pomfrey had him on a bed (which was dedicated to him after the amount of times he had used it) she slammed and locked the door telling everyone to go away and not disturb her.
About 4 hours later Poppy stepped away from the floo as Minerva, Narcissa and Draco stepped out, the three of them took in Poppy's appearance and were shocked at how dishevelled she looked and they were concerned as they saw how worried the Mediwitch was.
"I have given him a potion for the side affects of the Cruciatus curse, his cuts and bruises have been healed and dealt with but he has had to have a few blood replenisher potions and I think he might have fallen from a height because he has a few broken bones that look like they broke from height impact…" Poppy hesitated
"Poppy?" Minerva asked
"He is in a coma." She said seriously but sadly
Draco let out a sad sound and Minerva and Narcissa had a few tears drip down their faces, Draco walked over and sat in a chair next to Harry's bed and grabbed his hand and looked at his pale face, Narcissa walked to the other side of Harry's bed and stroked his hair affectionately, (Minerva went back to her office to talk to Kingsley who had been with the bunch of Auror's who had taken Lucius and his companion back to a higher level cell in Azkaban).
"You have to wake up Harry. Your friends need you, Teddy and Andy need you, Mum needs you." He said before whispering "I need you." He stood up and walked out to his quarters, lessons had been cancelled for the day but he needed to brew a few potions for the hospital wing.
Narcissa who had been listening to her son smiled as she heard the whispered part and looked down at Harry and said
"Make sure you wake Harry, you finally have the family you always wanted and if you didn't wake, it would break my son." She said to the black haired boy, she smiled gently as she thought about the look on her sons face, it was one of true affection and love a look she had never actually seen. She kissed Harry's forehead before she too left to her quarters.
