Chapter 25

"I have not told him that yet," Seto replied stiffly before turning to Harry, "I am sorry love, I was going to try and tell you this later on today...I just needed to work out how to tell you...I was not keeping it from you..."

"I know you where not, so much has happened in these past few days and you have told me so much already, I am not angry at you about it, besides you said you were going to tell me this afternoon right?"

"Yes I was, I was hoping to catch you before you left to visit your friend," Seto replied with a sigh of relief, "Well...I guess that there is no holding it back now Harry...you see...do you never think how strange it is that Professor McGonagall does all the work she does and more yet she only gets half the money she deservers and Headmaster Dumbledore treats her horribly?"

"Yes...I do..." Harry replied slowly as he eyed Professor McGonagall carefully, "But I...I thought that Professor McGonagall was in love or was married with Headmaster Dumbledore?"

"Not quiet Mr. Potter, I am married but you have the wrong man," Professor McGonagall said dryly causing Harry to blush and look away.

"Professor McGonagall, like Professor Snape, is a spy for the Dark Side," Seto explain softly as he leaned over and whispered into Harry's ear, "Professor McGonagall meet the Dark Lord, known as 'Tom' at the time while working in a muggle orphanage, they feel in love and had a daughter called Rose but a few happy months after Rose was born a tragic event happened and Rose was kidnapped...the last person to of seen her was Professor McGonagall and Headmaster Dumbledore who had come over to ask Professor McGonagall about becoming a member of the Hogwarts staff."

"Okay...so let me get this straight," Harry replied as his eyes widened in shock and surprise, "Lord Voldemort is really Professor McGonagall's husband and Professor McGonagall is just working here at Hogwarts to spy on the Headmaster?" Harry asked as the new information began to whirl around in his mind.

"That is correct Mr. Potter, I do not wish for any other children or parents to suffer the way I did and I know for a fact that the old lemon sucking fool placed Rose with a muggle family but will not tell me as he thinks it is for the greater good..." Professor McGonagall growled out darkly, "What worries me the most through was Rose's magic...when Rose was born she was blessed with power over the elements and a creature inheritance instead of 'normal' magic...I am worried what she and her family would of done when her powers and magical creature side would of done when they first started to show..."

"I think they would of loved her the same and just accepted it," Harry replied softly while trying to chase out images of the Dursley's came to mind, "I am sure that the old goat at least had the brains to put your daughter with a loving family so when the time ever came for you to get her back then everything would be fine."

Seto kept quiet as he gazed with eyes full of love and understanding at his mate as memories of Harry's letters filled with information about the true side of his horrid relatives came to the front of Seto's mind.

'He truly is something special' Seto thought as he gazed lovingly down at Harry 'To put someone else's needs before his own at a time like this...he really is amazing'

"Thank you Mr. Potter...I like to think the same...sometimes I hope I have Grandchildren out there in the world somewhere," Professor McGonagall said as she trailed off softly before shaking her head, "I am sorry, I got side tracked, I am here for three reasons. One is to give you both this."

Seto and Harry watched closely as out of her robes Professor McGonagall pulled out an official looking letter with the wax stamp of Riddle-McGonagall sealing the letter shut from prying eyes. Nodding slightly to Harry Seto held out his hand for the letter.

"This is an invitation to talk with my husband at our home this weekend," Professor McGonagall said as she placed the letter in Seto's hand, "To talk about joining forces and your places in this war."

"H...He will not try to kill Seto or anyone will he?" Harry asked softly as his eyes flickered worriedly between Seto and Mokuba, "I...I am really tired of this war, I have had enough of all of the grief and suffering it has brought everyone."

"We all have Mr. Potter, and no, this meeting is being set for this weekend due to the fact that my husbands...helpers will be given the night off to relax and enjoy themselves meaning that the manor will be totally neutral ground," Professor McGonagall replied with a flash of understanding in her eyes, "I must warn you Mr. Potter that during this meeting you might find out some...unexpected things..."

"I...That is okay, I think that it is about time that every dirty little secret came out of hiding and be faced," Harry said as he tried not to allow his nerves to show.

"Well said Mr. Potter, now onto the second point of business," Professor McGonagall said with a hint of a smile on her face, "Everyone in the castle besides Headmaster Dumbledore and Ms. Granger supports or at least will understand you both being together when they most likely find out about you both being together during breakfast today...plus no one can object about Professor Kaiba's treatment of Mr. Potter because his class has no homework or exams."

"Really?" Harry asked excitedly as he turned to gaze at his mate.

"Really, you see books and other materials for my class was either lost 5,000 years ago or band by Fudge, Dumbledore and their idiot minions," Seto replied with a chuckle at his beloved Harry's happiness, "Plus when I suggested that I find out some books for the students from my...personal library for the students to look at things got a bit...crazy..."

"Crazy? You call everyone screaming about how 'dark' this shadow magic is just because it has the word 'shadow' in Crazy? You call everyone screaming about how 'dark' this shadow magic is just because it has the word 'shadow' in its name while others demand for your head to be separated from your shoulders because you are trying to corrupt their children a 'little' crazy?" Professor McGonagall asked with a pointed look, "If it was not for the Headmaster stepping up with his manipulative ways you would be dead by now...in fact if the old goat ever gets a chance to kill you Professor Kaiba he would just so he could keep control over his 'weapon'."

Fear and panic suddenly struck Harry at his Head of House's words, his face quickly became pale in the flash of a second while his heart felt like it was pounding away like a big brass drum, his eyes went wide as his mind ran over just how much danger Seto and Mokuba would be in just by knowing him...Harry did not even want to begin thinking about what could happen to them if anyone tried to hurt them just because Seto and Mokuba knew Harry.

"Y-You are right...Professor," Harry stuttered out as he gazed unseeing at the wall opposite him, "Even if people find out that I know Seto and Mokuba then...I dread to think what would happen to them...but...but to think about what might happen to them if anyone like...Dumbledore...ever found out about Seto and I...about Seto...about us being mates...it is like you said Professor McGonagall...the Headmaster will kill Seto the first chance he gets...maybe...maybe me finding my mate was not really a good thing...maybe it was a bad thing because-"

Before Harry could finish his painful words a pair of soft loving tender lips landed on his own and kissed him. Tears formed within Harry's eyes as the feelings of pure and honest love washed out of the kiss and into his body, a familiar pair of hands slowly made their way to rest on Harry's waist filled with tender love and a strong protection. A few seconds later Harry found himself being pulled into a strong protective chest that made Harry want to melt into as the feelings of love, safety, protection and happiness washed over his body like a tidal wave.

A few minutes later the need to breath seemed to suddenly piece through the wave of Utopia emotions that had Harry warped up in. Letting out a depressed whimper Harry used all of his will power to reluctantly pull his lips away from the perfect lips. Luckily Harry found the owner of the perfect lips felt the same as him and they slowly parted ways but not without a few tender licks of each other's lips to try and keep the flavour of the other with them for as long as possible.

Panting hard Harry blinked a few times to regain his bearings only to find himself being held against Seto's muscular chest by a pair of protective arms. As his lust clouded emerald eyes looked over the equally pleasure filled face of his mate Harry found himself and Seto connected together by a thin trail of saliva hanging from the other's lips to their own.
