"Morning!" Lucy greeted the guild hall as she walked over to her partners, "Natsu, ready to leave soon?"

Natsu sprung, "Eh? O-oh y-yeah. We can leave."

"Are you feeling better?" Lucy crooked her head, "You seem worse than yesterday."

"He's fine," Happy stated.

"Yep!" Natsu agreed, "I'm great!"
"O-ok" Lucy said confused, "Let's go then… Bye guys!"

And the celestial mage, fire dragon slayer, and the blue Exceed were out the guild doors.

"Let's go!" Erza commanded a few minutes later, "Where's Juvia?"

"Oh, she told me that she had something come up," Gray explained, "But she's going to be here later, so we can tell her then"

"Huh, who would've thought that she would miss a day without Gray-sama!" Erza imitated, "But it's weird,"

"Ok, first off," Gray said, "That was a horrible impression. Second, it is weird."

"Where are you two off?" Mira questioned from behind the bar, watching the pair walk out the guild.

"We are spying on Natsu and Lucy," Gray explained.

"Yep," Erza added, "We're going to find out if Natsu sent Lucy that letter."

"Ah," Mira purred, "Tell me what you find out when you get back. I'm curious myself."

"K," Erza agreed, "We better go now, we might lose them."

"They're going to the train station." Gray corrected, "We will now lose them."

And with that, the pair went out the door."

A few hours later

"I feel sick~" Natsu groaned as he lay on the train seat.

"You really need to overcome your motion sickness soon enough, you know," Lucy stated, as this happened every time Natsu rode on any transportation, except Happy.

Why am I on a mission with Lucy? Natsu grunted to himself, thinking back to earlier that morning, I'm going to mess this up with Lucy! She already noticed that I'm acting weird.

"It's about an hour left," Lucy sighed, looking out the window, "You're going to be fine."

To the opposite side of their window as Erza and Gray in disguises. Erza in a Mato costume, the mascot of the Grand Magic Games, and Gray as a scientist with a hat and a mustache.

Happy, who was sitting beside Lucy, was looking at the pair with his head crooked. Have I seen them before? The male cat questioned himself.

"Lushi~" Natsu complained, "Help me~"

"How on Earthland am I supposed to help you?!" Lucy spat out.

"Just do something~" Natsu grunted, as the train went over a small bump, "Argh~"

"Then…" Lucy lead on, "Try thinking about something that'll distract you from the train ride, or try going to sleep."

"O-ok…" Natsu replied. The Dragon Slayer then found himself staring at Lucy whilst she was looking out the window. What am I doing?! He thought, If Lucy looks at me she- Natsu quickly looked away as Lucy was turning her head, and felt heat rising toward his face.

"How would've thought Natsu would be the first one to realize his feelings toward Lucy" Erza whispered toward her spy partner, getting a nod in response.

Happy was still staring at the pair across from their seat booth and decided to ask them if they'd met before, so he stood up and walked over to them. Luckily Lucy was still staring out the window.

"I've seen you guys before," Happy explained to the disguised pair, "But who are you?"

Erza and Gray looked down as they heard Happy's voice, then glanced at the other two mages, and decided to let Happy know it was them. They both slightly took of their hats for a few seconds.

"It's us, Happy." Gray told the confused cat, making sure Natsu and Lucy didn't hear him.

"We're spying on Lucy and Natsu." Erza added, "We'll tell you the reason once we get back to the guild."

"Happy!" Lucy shrieked, hurrying to get the cat away from the unknown pair, "I'm so sorry. He doesn't usually do this."

"No, it's fine." Gray said in a low tone, trying to disguise his voice.

"What do you think you were doing?!" The blonde scolded.

"I just told them a joke," Happy lied, knowing the pair would kill him if he would say anything about them spying, "They looked bored, I was bored, and I kept calling you but you kept looking out the window."

"Oh," Lucy said, convinced, and gave the cat a hug, "Sorry Happy."
