Lessons To Learn And Teach

Lesson Six – Listen To Your Elders

Gaius jumped as his door flew open hitting the wall and nearly falling off its hinges. He stared at Arthur who has Harry in his arms, the younger man was sweating profusely, his arms and the bit of his chest that was visible was splotchy and a violent red.

"What happened?"

"We were sparring and he started coughing and he fell and I took off his armour and he was just like this" Gaius moved the blankets off the medical bed and Arthur laid Harry down.

"Arthur!" Merlin called "Arthur move me in there!" Arthur looked at Gaius who nodded and Arthur went to help Merlin then he sat him on Gaius' workbench ignoring his wince of pain.

"What can I do?"

"I do not know, it looks like an allergic reaction but I do not know what to"

"Arthur can you go get me a shirt?" Merlin asked quietly and Arthur looked down at him

"No, whatever you know you say in front of me, I'm not leaving him"

"You hardly know him!"

"No I do not, neither do you but I feel I must protect him and so far I have not done that, I am not leaving him!" they glared at each other before Merlin sighed

"You need to put me beside him"

"You cannot do anything!" Arthur said exasperated

"I know what's wrong"

"What?" Gaius asked flipping through a book. Merlin gave Arthur a nervous look and sighed

"His magic looks different," he said quickly and Gaius' eyes darted to Arthur before going back to Merlin

"What do you mean?"

"His magic is a silvery green colour over the last couple of days it's been becoming a darker green. I thought maybe it was just him growing or something, but now it is as if it is being suffocated there is a dark blue layer. The magic that is in the earth and air, in our buildings and everything, it is suffocating his magic, his magic spikes but his body cannot handle the fight."

"He's a sorcerer? And you can see magic?" Arthur asked

"Can you do anything?"

"His magic seems close to mine maybe I can help him fight without too much damage to his body?"

"And you are a sorcerer!?!" Merlin could not bring himself to look at Arthur

"Try it" Merlin nodded and went to stand but fell with a gasp. Gaius went over to help him but Arthur was their first

"Thank you"

"I believe you are both what you have shown, but the second either of you hurts someone with magic I will tell my father" Merlin nodded

"I will never hurt anyone with my magic, and I do not think Harry would." He sat on the edge and bit his lip before taking Harry's hands. His eyes flashed gold and Arthur knelt stroking Harry's hair whispering to him.

Merlin let his eyes flick to Arthur and smiled seeing silver and gold swirling around the prince like a shield; Harry was protecting Arthur as well. Turning his eyes back to Harry, he saw his magic flow into Harry the silvery green of Harry and his bluish silver turning against the dark blue with other coloured flecks. The dark blue gathered, being pushed into one place and Merlin wished it away mentally connecting with Harry.

*You need to expel it from your body* he felt Harry's magic flare in response and his eyes switched back as there was a massive crash, all the pottery and glass was smashed and there was papers everywhere.

Harry has stopped sweating but his body was still covered in a rash and his breathing was laboured.

"His magic is fine the rest must be a reaction to something."

"What about what you gave him this morning Gaius?" Arthur asked as Merlin tiredly fixed the glass and pottery. "He was very hyperactive after that"

"Hyperactive?"

"Very" Gaius frowned and nodded

"I gave him something because he was ill this morning, but he did not listen to me when I told him that he should not attend to you." Arthur nodded, "It may have set him off, but I cannot tell what it was and there is a very limited range that does not have any of the ingredients in at all."

"Anything you can do?"

"I'll see, Merlin any ideas?"

"No it is nothing to do with his magic, but it is fighting whatever is going on." he yawned and Arthur moved his stubborn servant back to his room and left when he had fallen asleep

"Can I do anything?"

"Keep their secret?"

"I will, I meant to help Harry now"

"You can sit him up in a while I will make a slave that should lower the irritation to his skin." Arthur nodded and watched Gaius make a slave whilst he pressed a damp cloth to Harry's hot head and face.

...

Gaius exited Merlin's room after helping his young charge wash and shook his head seeing Arthur asleep one hand linked with Harry's and the other in his hair as he was lent back in the chair sleeping on his own shoulder. Harry looked back to his usual pale except for a few splodges. Gaius touched his forehead and saw that his fever was higher but it seemed closer to braking, hopefully.

"Sire? Arthur" he ran a hand through the blond hair and Arthur breathed deeply his eyes fluttering open

"Gaius?" he said gruffly, Gaius handed him a goblet of water and Arthur greedily drank from it

"Sleep well?"

"Not really," Gaius watched him stroke Harry's hand and forehead and sighed

"How was his night?"

"Fitful"

"Thank you for staying with him"

"I feel like I failed him, but I do not understand why" Gaius nodded. Arthur sighed and kissed Harry's forehead noticing the interesting scar. The door opened and Arthur let go of Harry's hand and hair as his father came in followed but another man, but all Arthur saw was blond hair.

"Gaius, I understand my son's stand in has come down ill"

"Yes sire, I think he may have had a reaction to something I gave him yesterday" Uther nodded and saw Gaius look at the man beside him

"Ah yes, Edward arrived yesterday evening, he heard of his look alike and wished to see him." Gaius nodded

"I doubt he will wake soon his fever has yet to brake" he said indicating to Harry and Arthur.

"Edward, my son I'm sure you remember"

"Indeed, even if he was a little might the last time I saw him." He smiled, his eyes sparkling with amusement as Arthur gaped at him then snapped his mouth shut and looked down at Harry then back. He had never believed everyone else when they said Harry looked like King Edward Potter but except for being taller, a bigger build, with blond hair and blue eyes they had the exact same face shape, Harry's cheekbones slightly higher, their hair was the slightly tamed but still wild and long style. Edward looked like a twin, if he had not been older, but the 'lighter' version of Harry. The man had magic, Arthur could feel it now, tingling his skin, he felt like Harry but weaker.

"Do you mind if I leave you here?"

"I can look after him father" Arthur said and Uther nodded leaving Edward knelt at Harry's side and stroked his hair back

"What have you gotten yourself into, my little one" he whispered and Arthur raised an eyebrow as the man pulled back slightly and frowned "I do not know of a illegitimate son, nor any other relation to me." He mused talking to himself and Harry. There was a thump and Merlin fell in, only Edward's quick reaction froze Merlin in his fall wide blue eyes looked between Edward and Arthur. "You should be more careful child" Edward said his magic placing Merlin in a seat. He looked towards Arthur "I can erase your memory of that if you cannot keep my secret"

"Sure why not one more" he sighed and Edward smiled. Edward looked between Merlin, Harry, Arthur, Harry, and back to Merlin to start again.

"Will he be ok?" Merlin asked the older man

"He will, his surroundings are just different, unusual for his body to cope, but he will get better, however he needs to be careful he will be very susceptible to any and every illness." Gaius nodded

"I was thinking that, how it does work I do not know and will not ask but I can probably make a potion that should strengthen his ability to fight illness."

"That would be a good idea" he nodded "I will encourage his magic to help his body heal but I will only do it slowly otherwise he will never gain the ability to fight illnesses, I would also say his reaction is to a flower"

"Bluebell?"

"Quite possibly." Arthur watched the man and Merlin watch over the small man as he drifted back off, they would both look after Harry whilst he caught up on his sleep. His dreams were full of magic and black hair, green eyes, pale skin, slim bodies, and blue eyes flashing gold.
