*Author's Note*

Well, I wanted to have this story done the day after Backwarder aired... but it sort of took on a life of its own. Which is why this "Tumblr Exclusive" quick one-shot is now finding a home here, and two weeks after the episode aired, to boot. Others probably beat me to the punch for this storyline, but I wanted to share my take anyway.

Originally, this story was supposed to just be Adrien's POV of getting the letter and dragging Kagami around London to find the pills... it evolved to include Kagami's thoughts on the weekend, as well as a more in-depth look at their weekend away. I have to say though, I actually had a lot of fun writing Kagami's perspective.

Please, feel free to tell me what you think.

Chapter 1

Adrien's thumb twitched against the folded paper in his hand.

"Read it on the train," Marinette had told him before running off.

"Something only I can give to her?" Adrien was in a daze. He had no clue what it could be. Something from London? Something to do with the British royals? That had to have been it, right? He was the only one going to the royal wedding that Marinette was friends with.

"Adrien?" Kagami stood in the doorway of the train. The question was spoken more like a statement, a simple call to draw his attention to her. No matter the situation, Kagami always seemed to speak as if she had no doubts; always sure of herself. The only time Adrien remembered that confidence wavering was after their first match, when he was falsely declared the winner.

"Sorry, Kagami. I just had to see what Marinette needed." Adrien joined her on the train, but stood just inside the doorway.

"And what did she need?" Kagami's eyes drifted to the note in Adrien's hand, before she caught his gaze.

"Not sure." He studied the creases of the folded letter. "She asked me to wait until I was on the train." He was on the train now. He'd be following her request if he opened it right then, but the train was going to leave soon, and he still had to get to his seat. Besides, he had the next two hours to read it. Placing a soft hand on the middle of Kagami's back, Adrien escorted her into the train car.

"Adrien, is everything alright?" Gabriel stood by his seat beside Kagami's mother, his eyebrows knitted together as concern and scrutiny coated his words in equal parts.

"Yes, Father. Sorry for the delay. I just had a friend see me off."

Gabriel appraised his son, and then Kagami. Without a word, he took his seat, and then Adrien showed Kagami to hers. As they settled in, Kagami's eyes again darted to the note in Adrien's hand before refocusing on the back of her mother's seat in front of her. Adrien's eyes also drifted to the note as he turned it over in his hands, trying to understand what could be so important for Marinette to leave it with him.

They hadn't left the station yet, but Marinette didn't specify when exactly he should read the note, just that he should do so while on the train. He was on the train. He was settled into his seat. It was probably fine to read her letter now.

He carefully unfolded the paper, and was instantly greeted by a doctor's office header across the top. Concern and confusion swirled through his head, but he quickly calmed his nerves. He didn't know the whole story yet.

The confusion and concern increased once he did. It was a prescription for constipation pills. There wasn't even a particular brand listed; the prescription looked like it was for any generic over-the-counter medicine. All the note specified was which drug should be the active ingredient, and what the suggested dosage should be.

"Why would she give me this?" Adrien read the prescription a few times, but it still didn't make much sense to him.

"I never told you this," Marinette had said as she handed him the letter. It now struck Adrien as such an odd thing to say. Of course she had never told him about the prescription before. Why would she feel he needed to know about that? Did she have a chronic condition? Was she trying to tell him of her medical problems? Was this her way of letting him know that she thought of him as a close enough friend to be trusted with something like this?

"What I want more than anything else in the world is written on this piece of paper." Adrien read the prescription one last time as he repeated Marinette's blushing confession.

"Is something wrong?" Kagami leaned over to look at the letter, but Adrien had already pressed it against his chest. "Whatever it is must be important if you want to keep it such a secret." There was a challenge in her statement, but Adrien didn't cave.

"It's not my secret to tell, Kagami. Marinette trusted me with this. I just don't know why." He played back the last thing she said to him before running off: And only you can give it to me. "I know she had a reason to make sure I had this before going to London, but I just can't figure out what it is."

"If you let me see, I could help you figure it out." Kagami softened her voice, trying to coax the letter from Adrien. Instead, he shook his head and tucked the letter in his pocket.

"Thank you, but she trusted me with this. I have a couple hours before we're in London. I'm sure I'll figure it out by then."

"Well, if you need a female perspective to try-"

"Father?" Adrien zoned Kagami out as Gabriel shot out of his chair. Without a word, Adrien's father stormed to the conductor, had some heated words, and then vanished into the bathroom.

"Ladies and gentlemen," the conductor announced, "we have a sick passenger on board. Our departure will therefore be slightly delayed until further notice."

"Father." Adrien poked his head around his seat.

"A tree planted in too small of a pot may grow accustomed to the knotting of its roots," Kagami's mother commented calmly from her seat. "However, once the tree is moved to a larger space, and those roots can fully stretch out, as they should, the tree may feel sick and uncomfortable until the roots adjust to the room and new soil."

"Oh." Adrien's confusion spiraled further. Were all women confusing? How did he not remember that about his mother?

"What my mother is saying," Kagami offered, "is that your father isn't going to feel well in public after staying so close to home for so long. He'll get over it though, and realize how much better it is for him to be outside your family mansion."

"As long as he'll feel better." Adrien knew there wasn't much he could do to help his father, so he plugged his headphones into his phone, played some of his favorite piano concertos, and drifted into his mind to try to figure out why Marinette would give him a prescription for over-the-counter constipation pills.

Until next time...

*Author's End Note*

First of all, how do you like this new A/N format? I saw BunniElyse design hers this way, and I thought it looked so clean and professional. So I figured I'd model off of her.

Anyway, as I stated above, I wasn't expecting the story to go the direction it decided to go. What was originally going to be a 1000 word short posted to Tumblr on Feb 13th turned into a 10,000+ word story that I'm still putting the finishing touches on for the final chapters. It will most likely be closer to 13,000 words when all is said and done. I'm trying to keep everything in bite-sized chapters this time though. So, while a rare 2500 word or so chapter may sneak in, most of them will hover around 1100 words.

Also, since the story is nearly done anyway, I should be posting fairly quickly, about every three days or so, which should be enough of a lead time for me to get those last chapters done and the middle ones polished. So... next chapter should be up on... let's say Thursday, Feb 28th. See you then!

In the meantime, thank you for spending this time with me, and any/all reviews are appreciated.
