Authors Note: so this is just something random that came to me last night because I was doing this RP thing as Diane so I'm like why not write a fanfic with her just for no reason lol but I didn't want to mess up my other fics so now there's this haha. Idk where I'm going with it yet, I'll only really continue if you guys like it otherwise I won't bother. This story though is mostly about the Struggle between Catherine and Diane not just for Henry but like in general as well. Henry will obviously be in a lot if I continue and chances are I'll do Cathry eventually because they are my every happiness but yeah lol back to the point - sorry if you don't like my version of Diane, I'm making her a little..#psychocentral lol and I noe the way I'm portraying their relationship here may seem weird but like yeah in case it's unclear she's just doing it to get in Catherine's head and psych her out because in this story she's mega ambitious and wants the throne for herself

Diane and Catherine had never really spoken before, it was still early in the Queen's marriage to Henry and neither had given him a son as yet. Diane was publicly recognised as Henry's mistress only recently but the blonde had known of her existence for quite some time. Trying for an heir had strained their marriage to the point of no return, the days of the two of them being young and in love with no care in the world were well and truly over. The King had turned to his mistress for comfort and an ego boost. She made him feel like a man in ways his wife didn't know how. Through no fault of her own of course, Catherine was still young, only 17 and in the midst of discovering herself; in all aspects. Where as Diane was almost 20 years older and stunningly beautiful, moving with a practiced grace and patience, she was wise in a certain kind of way and knew how to make a man feel like a King and a King feel like a God. As much as she despised her to the very core of her being, even Catherine couldn't deny the allure she had, her ever gesture screamed sexy and her eyes stayed solely on the king, a fact she knew her husband revelled in.

Her Majesty's heart ached at seeing them together, so openly affectionate made her stomach churn, that should be her holding his hand, standing by his side. She loved him and for so long she was sure he loved her too, why was he doing this to them? Why he insist on humiliating her in this way she would never understand.

She avoided Diane when she could, aside from the occasional hateful glare. Which of course only gained her an amused smirk in return. She was quite content to avoid them the rest of her life but unfortunately the fates had a different plan.

Catherine was on her way to visit Henry to discuss the few political matters she was able to discover information about, insistent on being a part of her court despite her husbands efforts to keep her excluded, when she caught sight of Diane ordering workers around the rooms that were once her own. Unable to quell her curiosity she went to have a further look to find they were ripping the tiles off of the floor.

"What the hell are you doing?!" The Queen asked as she entered the room, causing all the servants to stop their work

"None of your concern" Diane answered with a dismissive flick of her wrist, not even bothering to glance over at her lovers wife as she motioned for the tilers to get back to work.

"I am Queen. I have the right to know what happens in my court now, answer my question" demanded firmly.

With an irritated sigh the Kings official mistress walked over with a design swatch to show the Queen. "I am personalising my new rooms. The new tiles shall have an interlocking 'D' and 'H' to represent Henry and I and our unbreakable bond." She explained happily, not an ounce of sensitivity to the fact that it was the first initial of Catherine's husband she was setting in stone with her own. "Don't worry your majesty, the King has approved the changes he loves the idea" she added cruelly after a few moments had passed and the Queen was still at a loss for words at the sight before her; would this torture never end?

Not wanting to spend another second in this soon to be contaminated room and having got what she wanted Catherine turned to leave but not before muttering a passing 'endearment' under her breath.

"Whore"

"I'm sorry child, you must speak up. What was that?" Diane snapped upon hearing her whisper, a smile fixed to her lips that Catherine supposed was meant to look kind or innocent, though it was devoid of any warmth and brimming with a sick type of maliciousness.

"I said you were a filthy low grade whore not fit breath near tiles you're removing." The Queen retorted without missing a beat as she turned around to face her, ordering all the servants out with a single gesture before adding with an empty smile of her own; "Shall I say it again or did you catch it this time?"

The older woman was shocked for a moment, not expecting such ferocity from a girl she'd really only seen as meek and shy before today. Perhaps the tales Henry told of his wife's temper were not as exaggerated as she first thought. "You certainly are a fiery little thing aren't you? Tell me are you always this hostile or is it just me" She smirked, receiving nothing but a pointed glare from Catherine. Annoyed by her lack of response Diane decided to teach the young consort a lesson for daring to interrupt her schedule. After a few moments of the little starring contest that ensued the brunette burst out in fits of laughter, laced with a vindictiveness that would've made the more intuitive of listeners cringe. "Oh you poor child, oh you really love him don't you?" She asked almost in tears from her amusement, not giving the Queen a chance to answer before her tone turned cold and serious "It must sting to know it will be forever unrequited"

"Do not speak of things you do not know" Catherine barked back, saying the first thing that came to mind, though it turned out to be possibly the worth thing she could've said. As her opponents smile began to resemble that of a Cheshire Cat.

"Oh but I do know Catherine" she informed with a giddy excitement as she prepared demonstrate the cruelty she was capable of as she slowly made her way towards Catherine, getting so close that the Queen was forced to step back. "Henry has made me privy to your every dirty little secret." She drawled, smirking as Catherine's back hit the wall and she had the younger woman trapped like prey. "From that particular spot on your neck that drives you wild" she continued, her finger ghosting over the spot in question to prove she knew its whereabouts but daring to let her hand graze the Queens neck, nor touch her at all, not yet at least. "To that heart shaped freckle right under your well..we both know where don't we?" She smirked, revelling in the way she was making the blonde uncomfortable, her hands coming up to rest on the wall either side of Catherine, preventing any chances of mistake. "Tell me darling does it bother you that every place he's ever touched you he's touched me first?" She whispered, her breath hot against the teenagers skin as she whispered in her ear. "That every sweet nothing he whispers in your ear whilst he uses you to breed himself an heir has already been said to another?" Diane continued to taunt. "That every little thing he does to make you scream he learnt from me, right down to the way he twirls his tongue" she added finally before twirling her tongue along the length of Catherine's earlobe, similarly to the way Henry had done in the past.

"Does it bother him that all the lessons he learned from you were taught to you by a hundred others? That he's sharing you with half of France" she retorted, doing all she could to remain composed and unaffected. She knew what this was and she was determined not to back down, not to give in to her temper.

"Oh, now, now, little Queen." The brunette tusked mockingly before leaning in even closer and whispering venomously; "are you really in any place to judge others on being shared? Florentine whore"

"Get the hell a way from me you disease infested slut" Catherine spat, pushing the taller woman away from her. There was much that she could take in stride when it came to taunting, but never that. Diane took about ten steps back but her sickly smirk remained intact.

"uh-oh looks like I may have hit a nerve" she gushed in feign worry "I guess the rumours are true after all" the brunette added with a twisted giggle.

"Watch your tongue" the Queen roared "or I'll-"

"You'll what?" She interrupted in amusement. "Honestly Catherine, as much as you wish to deny it we both know Henry would sooner see you hanged then allow you to lay a hand on me" Diane announced confidently.

Catherine snarled at her bitter enemy but she couldn't help the doubt sinking into her bones that she may be right. "He wouldn't dare I am the Queen of France I am-"

"A foolish child who's uncle bought her a title but you're Queen only in name little one and everyone knows it" her husbands mistress stated, as if it were the greatest truth the world had to offer, holding her hand up to stop any further challenge from her majesty as she walked over to her once more. "Just as they know I am the True Queen of France" she snarled as she invaded Catherine's space "you're just an Italian girl and nothing more..you'd do best to remember that, my sweet" she smirked before kissing the younger woman's lips firmly, revelling in the outrage on Catherine's face for just a moment before taking her leave.

Leaving the Medici girl with her fingers pressed to her lips in shock ad her words echoed through her mind.

'You're a Queen only in name little one and everyone knows it'
