They investigate the train

After finding a spare simple green dress in the train's luggage compartment and changing, Natsu/Wendy's first thought was to find the jerks that tried to kill him/her and Carla. However, the much more pressing issue was what happened to the passengers. The train was completely stopped in the middle of the forest and with the obvious exception of Natsu/Wendy and Carla, the train was empty. Natsu/Wendy even tried to smell the air to find them,,but to no avail. It was if there never were any passengers on the train.

Then, they made a startling discovery when they made their way to the engine room. There, they found a strange crystal, similar in structure to a lacrima, shattered in pieces. Even more so, the engine room was completely empty. However, when Carla took a closer look at the crystal fragments, she was frozen in fear.

"What's wrong Carla?" Natsu/Wendy asked concerned.

"This is an Illusion Crystal. Those brutes must have planted it here from the very start after we received our package from the courier." Carla said fearfully.

"Wait, so all the passengers and workers were all fake?"Nastu/Wendy asked confusedly.

"Yes, but the illusions were completely sentient. They believed that they were real to the point that one of the passengers actually bought that dress you're wearing and that the conductor drove the train to this point." Carla explained.

"So why are you acting so scared Carla?" Natsu/Wendy asked.

"Because Illusion Crystals are extraordinarily rare to the point that very few have at least one in their possession." Carla said.

"That still doesn't explain why you're looking so scared Carla." Natsu/Wendy said impatiently.

"This means that they were stalking us the whole time and planned everything from the beginning while we were none the wiser. All they needed was to separate us."Carla said utterly horrified.

"But, they could have waited the entire trip right? So their plan was flawed if we were still awake."Natsu/Wendy said confidently.

"They probably **** my food with sleeping magic and **** yours with a powerful diuretic; that way it was only a matter of time before we would be separated." Carla said appalled.

The news that they's been ****, tricked, and lied to on this scale, caused Natsu/Wendy's anger to rise exponentially. Without any warning, Natsu/Wendy suddenly unleashed an incredibly powerful Sky Dragon Roar that belw the engine room to smithereens, much to Carla's shock.

"WHAT'S WRONG WITH YOU CHILD?! You're acting like Natsu!" Carla yelled incredulously.

What will Natsu/Wendy do now?
