When morning finally came, Natsu and Lucy stood under the small vent in their cell.
"How are we gonna do this?" Lucy said scratching her head as she stared up, a small frown on her face.
"Erza said to put this thing on it…" Natsu said taking a small circular device from his vest pocket.
Lucy took a few steps back from it as he pressed a few buttons making it start to beep.
"W-What is that?" she stuttered.
He looked at her and grinned, "It blows up… I think."
She blinked as he threw it upwards, it landed perfectly, making a quiet high pitch squeak before blowing off the top of the vent. It came down quickly bouncing straight of Natsu's head.
"Where did Erza even get that?!" she said moving closer to the hole in the ceiling. Natsu shrugged, "I don't know, she's Erza!" he quickly grabbed Lucy's waist lifting her up and pushing her through it.
"N-Natsu!" she protested as she was shoved into the metal tunnel.
"Help me up, Luce." He replied, holding his hand up towards the scowling blonde.
"Tch." She whispered, grabbing his hand and pulling.
He didn't move.
"C'mon Luce."
She yanked even harder.
"For god sake Natsu!" she strained.
He rolled his eyes, jumping up and pulling himself through the roof in a matter of seconds.
Lucy opened her mouth to tell him off, but he'd already started crawling down the metal tunnel away from her. She bit her lip and followed him.
"They should be somewhere down here…" Natsu said, "Wait no! Other way, other way."
Lucy froze. "I can smell Lug nuts! Turn around…" Natsu said turning to face her.
She sighed and turned around crawling back the other way. After a few minutes, Lucy saw a light.
"Hey Natsu, a light!" she whispered moving closer to it.
She saw Cobra, standing next to some kind of cage made of metal mesh wire.
"Time for dinner, Cubellios." He sighed taking a few steps towards the cage. Lucy couldn't see what was inside of it but she heard a loud hissing as he approached it. She stopped, trying to get a better look.
"Oof!" Natsu gasped, as he went head first into Lucy's behind. He hadn't expected her sudden stop.
Lucy's eyes went wide as she squealed. "P-Pervert!" she scowled.
"What!? That was your fault!" Natsu said, his face still pressed against her.
"GET OFF!" she yelled, tumbling forwards.
"Who's there?!" Cobra's voice came.
"Sh*t!" Natsu whispered, pushing Lucy forwards down the vent.
They clawed their way down the tunnel as fast as they could.
"Keep going, Luce!" Natsu growled, as a siren turned on.
They stumbled round bends and crawled down dips until they heard a loud shout.
"I tell you, Flame brain's done this!" Gray's annoyed voice travelled down the tunnel.
"Hurry, Gray!" Juvia said worriedly, as the siren got louder.
"Gray?" Erza shouted.
"Erza!" Natsu shouted.
Suddenly the tunnels were filled with voices.
Lucy lunged forward around a corner banging heads with Erza, Grey and Gajeel.
They all cursed loudly.
"Where the hell are we going!" Gajeel hissed.
"Who set off the alarm?!" Grey scowled at Natsu, over Lucy's shoulder.
"Shut up! Idiots!" Erza said.
"We're going up there." Jellal said calmly, behind Erza as he pointed upwards.
Lucy looked up to see a tunnel going straight up. A small metal ladder was attached to the side.
The siren suddenly stopped.
"We have to go." Erza frowned.
Gray and Gajeel both moved forwards putting their weight on the last slab of metal under the ladder.
"No! Wait!" Lucy gasped, the floor cracked then creaked.
Gray and Gajeel went straight through the floor, triggering the other tiles to become loose.
The whole group fell to the floor.
Lucy laid on the stone floor. They were in one of the main hallways. Her ears buzzed and her head felt heavy and dizzy. All she could do was lay there waiting for the guards.
They had failed.
