______________________________________

Marinette stared at the akuma fluttering inside the jar that Adrien held. She was still trying to wrap her head around this whole thing.

Adrien...he had the akuma this whole time, meaning she was able to change back. So why did he keep it hidden from her? What in the world did he benefit from her staying like this?

"You...You had the akuma this whole time?" She asked the question still trying to believe it. When he nodded it only confirmed that what she was looking at was true.

Marinette felt a bit of anger rise from within her, all the times she asked about the akuma. All the times she spent searching for Flashback. The fact that he kept putting off the search telling her not to worry.

She needed the truth.

"Why..."

Adrien looked up at Marinette. "What was that?"

"Why did you lie to me?!" She shouted. "How long have you had that thing?! What reason do you have for keeping the younger me here?!"

Adrien heart ached at the crack in her voice as it seemed she might start crying. "I...I know you're mad and...you have every right to be giving the amount of times I...shut you down about anything regarding the akuma, but just let me explain.."

Marinette crossed her arms as she stared at the blonde with a glare. "I'm listening..."

Adrien sighed before continuing. "Remember that day I got hurt? The run-in that I had with the akuma....well that was the night I caught it and I was going to have you purify it when I got back but...."

~~~

"Hello Chat Noir"

The hero in black turned around to the sound of a woman's voice and wasn't too surprised to see Flashback standing there. Quickly he pulled out his staff and prepared himself for her next attack.

"What's the matter? You seem on edge?" The brunette akuma spoke softly, but wickedly.

"What did you do to Ladybug?!" Chat shouted at the girl.

"Actually it's what YOU did to Ladybug." Flashback said as a matter of fact.

Her response caught Chat Noir to raise an eyebrow not having any idea of what she was talking about.

"Well I guess there's no harm in telling you it's not like you'll remember anyway..." She said with hidden mischief. "I'm sure you've seen what my goggles can do. I have the ability to turn the clock back on anyone, physically and mentally, but....I don't control how far the clock goes back."

While the akumatized girl spoke Chat spent most of the distraction to try to figure out where her akuma was hidden. He thought about the goggles, but something about that didn't seem right.

Flashback walked away from the feline hero who kept a firm grip on his staff as she continued. "The beams from my goggles allow that person to change back into the age where the closest person that cares about them feels like they made their biggest regret. Judging by how close you and Ladybug are I'm assuming you're that person for her."

This comment caused Chat to stop searching as he looked back up into the eyes...or goggles of the akuma.

"What makes you think that?" He asked.

"Let me ask you this, since our last encounter have you been having visions of the past suddenly popping out of nowhere? Have you been finding yourself flashing back alot recently?" She asked with a grin.

Chat's eyes widen and that gave her the answer she needed.

"I see....well ill tell you a secret......the beam hitting Ladybug wasn't meant for her,but it was meant for you or at least it WAS meant for her but she pushed you out of the way at the last second, I sent her back to the time where your biggest regret involving her took place. So tell me Chat what IS your biggest regret with Ladybug, perhaps you missed you chance at confessing your love or maybe you abused her in the past."

"I've NEVER hurt her and I never will!" Chat said slightly annoyed and angered by the accusation.

"Then what WAS it?"

Chat thought for a moment. Marinette was fifteen, what was it that he regretted about her at that age. It was the same time he meant her when she was Ladybug and when they meant in class for the first time. He couldn't really think of when he did anything with her that he regretted. In fact they never really spoke to...each other.

He never got the chance to know Marinette at the age. He didn't hang out with her like he did with his other friends he didn't even know what she was like at that time and he had been too hooked on Ladybug to think about any other girls at the time.

But...she was Ladybug that whole time.

It wasn't until a couple of years later he realized how much he really liked Marinette, but he always brushed it aside due to his affection for her alter ego.

If Adrien was being honest with himself he's liked Marinette from the start, but he never acted on those feelings and he couldn't help but wonder how those years would have gone if he did just that and acted on those feelings, especially since he knew that she had a crush on him.

It was silly, but sometimes he wished if he could go back and give her the love and affection she deserved back then as much as she did now.

If he could let her know that he had feelings for her the whole time, feelings for both sides of her even before she realized it.

"I don't understand....how does pushing people's ages back help you?"

"It doesn't. Time is a precious thing, once it's gone it can never be brought back....I had to learn that the hard way....." Flashback looked down at the watch on her wrist as she rubbed a thumb over it and a single tear came down her masked face. "I want everyone to know the feeling of regret...."

Chat Noir stared at the watch on her wrist. That had to be where the akuma was hidden.

"If you're not going to indulge me, then I guess I'll just have to find out her age when I take Ladybug's miraculous!"

Thrown off guard by the sudden rage in her voice Chat wasn't fully ready when Flashback suddenly charged at him and tackled him to the ground.

He pressed the bottom of his feet against her front and launched her off of him. Flashback managed to land on her feet and began throwing punches at the blonde which he managed to dodge. Each of them trying to look for an opening, a moment where the other would slip giving them a chance to attack.

Chat glanced at the watch on Flashback wrist trying to decipher a plan on how to get the watch. Unfortunately for him, this granted Flashback the opening she needed.

Using all of her strength she kicked him in his chest causing the blonde to hit the ground with brute force. Chat Noir hissed in pain as gripped his shoulder that had hit the pavement hard enough to injure him.

Flashback pinned him down to keep him from moving and grabbed the arm holding his ring. A familiar purple light appeared around the girl's eyes and she gave a wicked smile.

The feline hero had to think fast he looked around for anything that could help him. He had dropped his staff and it was too far too reach.

Then an idea came to mind.

"Any last words before I take your miraculous?" Flashback asked with a grin.

"Yeah...just one." Chat responded matching the girl's smirk. "CATACLYSM!"

His hand was pressed against the concrete below them and it began to crumble. Chat Noir and Flashback fell into the room below along with the debris.

Flashback started to cough from all the dust as she struggled to get up. In that moment Chat Noir quickly got up from where he had fallen and snatched the girl's watch off her wrist before throwing it on the ground to break it.

The dark butterfly fluttered from the broken watch and Chat caught it between his claws to keep it from escaping.

Now the question was: how was he going to get this all the way back home to his Lady?

"Here....use this." The girl who was previously akumatized as Flashback held a jar that she had found lying on the ground in the room that they had both crashed in.

"Thanks." Chat put the akuma into the jar and sealed it closed before turning his attention to the victim.

She was now on the ground near the broken watch that had held that wretched butterfly. She picked up the broken pieces cradling them in her palms.

"Don't worry, once I find Ladybug. She'll use her cure to fix everything and your watch will be as good as new." Chat said kneeling in front of the girl. "What's your name?"

"Cheyenne..." The girl said timidly. "This watch....it belonged to my grandfather. He....passed away some time ago..." Tears started to fall from her eyes. "I...I don't know how this happened, one minute I was looking at his picture in my room and the next I'm here."

"It was Hawkmoth." The Cat responded. "He took advantage of your emotions and akumatized you."

"I wished that I had more time with him." The brunette confessed. "If I had known that he wouldn't be with us anymore I would have spent more time with him....I would have savored each moment....but now he's... he's gone and he's not coming back....all that time I could have been there....it's gone...he's gone"

Cheyenne started to sob clutching the watch close to her chest.

"Hey....just because he's not around anymore that doesn't mean he's gone." Chat said catching her attention. "Instead of thinking about the things that could've happened, why not remember the things that did happen. I'm positive that where ever your grandfather is he wouldn't give up those moments for anything and he wouldn't want you to live your life in regret..."

Chat stood up and offered his hand helping the brunette on her feet. She used her free hand to wipe away her tears and tried to give the best smile she could before glancing down at the broken watch.

"Make sure you hold to that, once Ladybug's cure kicks in it'll go back to how it was. I'm sure there are people out there worried about you and wondering where you are. Why don't we go find them and let them know that you're okay?"

Cheyenne nodded and Chat carried her to her destination.
