~Lloyd's POV~

"Focus, Lloyd," Y/n ordered gently. "Bring all your attention towards the energy at your fingertips."

"I'm trying!" I snapped. "We've been at it all day. Can't we take a break?"

Y/n sighed, then took my hands in hers.

"Lloyd, I've known you for a long time, and I can tell something is bothering you. If it will help, you can talk to me about it."

Y/n was right. There was something on my mind, and although I shared everything with Y/n, this was something I didn't know how to talk about. After all, turning more than half a decade older in one day is not a normal thing. 

"I'm here for you, no matter what's going on, and I'm sure your powers will be easier to access if you free your thoughts a little."

I thought about that for a moment. I breathed a heavy sigh: of course I couldn't hide anything from my best friend.

"A lot has changed in such a short period of time. I...I look different, and sound strange, and I barely even recognize myself. And now that I'm older, there's a lot more pressure on me than when I was a kid." I sat down against the rim of Destiny's Bounty, my head in my hands.

"Just because your body aged forward doesn't mean your mind did," Y/n said, sitting beside me. "You can't expect to magically become ready to face your father."

"But Sensei said—"

"I know. He may think the final battle will be closer now, but that doesn't mean it will be. Yes, you're stronger now, but you still have a lot to learn."

I sighed again. This was all so confusing. I opened my mouth to say something, but nothing came out.

"What is it?"

"I...I can't stop thinking about this. It's selfish of me, but..."

"Yeah?"

"I wish you had been changed with the rest of us. I know you're here for me, but it doesn't feel the same when we're two different ages."

Y/n was technically only a few months younger than me. We had been best friends for ages; we met before I was enrolled in Darkley's School for Bad Boys. I would get lonely there, so she'd climb into my room through the window to cheer me up. When she told me she wasn't going to visit me as often, I didn't realize it was because she had become a ninja. She was a lot stronger than me, and was able to participate in the missions with the rest of the team.

*Flashback*

Jay wouldn't let us use the Tomorrow's Tea on the Grundle, because it would make Y/n and I age forward. But the tea got knocked out of his hands, and onto my lap. Y/n and I glanced at each other, realizing what we had to do.

She leaped up onto the counter, and I tossed her the bottle. She threw it at the Grundle, and the glass broke, allowing the tea to work its magic. The Grundle thrashed, and its tail swung around violently. It knocked Y/n out of the way, into the opposite wall.

While the tea turned the Grundle, me, and the rest of the ninja older, Y/n was left without aging at all.

*End of flashback*

"We're not two different ages. You're still the same age on the inside."

She gave me a hug, which was a lot more difficult for her now since she was so small compared to me, but I thankfully managed not to crush her. 

"Promise me something," I said.

She put a delicate hand on my shoulder. "Anything."

"We'll stay friends, no matter what happens."

She nodded. "I wouldn't have it any other way."

~Y/n's POV~

Uh-oh. I had just made a promise that I probably wouldn't be able to keep. I mean, of course I wanted to stay friends, but part of me knew I wouldn't be on the team forever.

What Lloyd and the rest of the ninja didn't realize is that I had occasionally been disappearing for certain amounts of time, then reappearing before they got suspicious. Lately, my trips have been more frequent, and I feared that someday I would have to leave for good.

In that exact moment, out the corner of my eye, I saw the shell I always wore in my hair start to shimmer—the signal that I was needed in another world. I quickly covered it with my hand, hoping Lloyd hadn't noticed. Thankfully, it was Zane's turn to train Lloyd, so I could escape for a bit. 

"Good morning, brother and sister," he greeted. "Are you ready to learn the ways of the ice wielder?"

"Yeah, sure Zane," Lloyd answered, standing up.

Zane glanced at Lloyd, then at me, then back to Lloyd. "I sense your emotions are not in the proper state."  

"Heh, heh. Can we talk?" I asked. I turned Zane around and brought my voice down to a whisper.

"You guys really need to stop treating him like he's your age."

"That's what is upsetting him? That's a relief. I thought he was shaken about last night."

"What happened?"

"Cole and Jay started talking about how to deal with bo--"

"Ew! Forget I asked!" I interrupted. "All I'm saying is that you need to put less pressure on him. A lot has changed in such a short period of time, and you guys are making it worse."

"I understand. I will do my best to remind the others that Lloyd is still young-minded."

"Oh my first spinjitsu master, I can't even imagine the conversations he's had to listen to in your shared bedroom."

While I shared a room with Nya, Jay, Kai, Cole, Zane, and now Lloyd, all were cramped up in a single room. Lucky Sensei Wu got a room to himself.

"That sounds like an exaggeration. Surely you can think of the things—"

I shoved my hand over his mouth. "No, I really can't. Please don't enlighten me."

"As you wish, sister."

"See you around Zane," I said, then left the area.

I headed below deck, looking for an empty room. Nya was in our bedroom, so I headed to the bathroom. I made sure no one saw me enter, because then they'd be confused when I wouldn't come out for a few hours. I left the door unlocked, in case someone needed to get in there after I left.

"Okay, Ripple, it's safe to come out now," I whisper.

A small, dolphin-like creature floats out of my pocket. "It's about time! Come on, Ladybug and Chat Noir are probably waiting for you."

I nod, a smile spreading across my face. "Ripple, fins up!"

** Your transformation: **

[There should be a GIF or video here. Update the app now to see it.]

(I know my editing's trash, but that frame-by-frame reanimation took forever so I'm semi-proud of it. You can imagine your transformation differently if you want, of course)

Now dressed as Dauphine Bleue, I tap my miraculous three times, and watch as my image in the mirror begins to fade. In the blink of an eye, I was in another world.
