Time travel is a complicated equation to solve, but I’m sure if we put our heads together we’ll come up with something!”
Five raised a skeptical eyebrow. “And you’re just going to do that out of the goodness of your heart? I’m not even old enough for high school yet.”
“Well, we’re all heroes for a reason, no? What good are we if we can’t help a single child in need?” Nedzu pointed out with a pleasantly neutral smile as he sipped his tea.

Haruhi said to the stranger, "The food's good, isn't it? Have you tried the small quiches?"
She'd spoken English on the assumption that most people in the room would likely understand it, but when the man turned it became apparent that he was Japanese. Haruhi knew this because she recognised his face. It was the face of Japan's ace skater, Katsuki Yuuri.
"K-K-Katsuki Yuuri-senshu!" Haruhi clapped her hand over her mouth, feeling the blood rise to her face.
"Ah," said Katsuki. He was different off the ice. His spectacles reduced the impact of his eyes, and the shape of his face was somehow softer, less distinctive. "Do I know you?"

Hurt/Comfort

Now. What Phoenix is expecting is for Luke to roll his eyes and call him old or overbearing or something like that. He's expecting Luke to brush him off or maybe even insult his hair, because that's what everyone else in this town has seemingly taken to every time he says something they mildly disagree with.
What he’s not expecting is for his vision to rapidly alter as soon as Luke answers, and then for not one, but five Psyche-Locks to come rattling down around him.
“Mr Wright?” Luke frowns. “You’re looking at me funny.”
(...Okay. Okay. This is... fine).
or: phoenix forgets he has the magatama with him in labyrinthia - until luke has something to hide.

Maya pulls at Nick's suit jacket again just to annoy him, rather than to get his attention. “I need to talk to you! I've only just figured it all out because I got my memories back and remembered I’m a spirit medium, not a baker.”
“That’s funny,” Nick frowns, “Because I got my memories back and remembered you hit me with a pipe.”
“You were fine! It’s not like you haven’t been hit in the head before,” she says pointedly, thinking back to the infamous fire extinguisher incident of two years ago. “I needed to talk to you alone, because I figured it out! I know why Layton and Luke seem so weird!”

"...and that's a left and- ughhh!" Phoenix stopped walking when Luke promptly about-face-turned straight into his stomach. A beat, then muffled, "We're at the main hallway again."
"Again?" Espella peeked out from behind him to note that, indeed, they'd gone in their fifth circle and had ended at a different part of the hallway. "Ah, I see... is there even a way out?"
"There has to be!" Luke furiously scribbled on the pages of his notebook; marred with five previous attempts of mapping, it was getting too crowded to read. "Ugh, this is so unfair," Luke growled, voice warbling, "the Professor was always better at these than me...!"

As he thought about it, he realized a few things. First, that the destines of Mobius and the Mushroom World would be forever entwined because their worlds were forever entwined—and the destiny of their heroes was similar, no matter which way he picked. Secondly: despite his strength, and the strength of his brother, Mario and Peach wanted them to stay, not because they were helpless, but because they wanted them to grow up safe.
And thirdly, he really didn’t mind that prospect.
Somehow that was the strangest part about this.
