Leo looked around the corner. The hallway appeared to be bare. He gestured to his brothers as he stepped into the hallway. Don creep out while Raph waited for Mikey to step out so he could get in. Seeing that his brother wasn't going to move, he shoved him. Mikey yelped as he stumbled out, almost instantly covering his mouth. Leo drew his Katana's, Raph his Sai's, and Don his Bo staff. They stood for a moment.
When nothing happened, Leo said, sheathing his katana's, "Nice going, Mikey. You could have set off an alarm or something."
"Actually, there aren't any alarms in here." Don said.
Leo gave him a I-didn't-need-to-know-that look. "Next time, be more careful and silent."
"Sorry, but Raph pushed me." he whined.
"No one feels sorry for you, Mikey. You wouldn't move." Raph said. "Now which way, fearless leader?"
Leo ignored the last statement and began to head to the right of the passageway they came down but stopped. He thought he heard something. Other than Raph's quiet threats and the beeping from Don's Shell-cell as he tried to get blueprints of the lab, Leo heard nothing. He shrugged his shoulders and began to continue walking.
'Go another way.' Leo spung around, unsheathing his weapons. Nothing was behind him.
Don, Raph, and Mikey looked at him surprised. "Dude, are you o.k, bro?" Mikey asked.
"You look a bit-pale." Don commented.
"I'm fine." Leo said,
He turned back only to hear the voice again. 'Go another way.' With a deep sigh, Leo did exactly what the voice and headed another way. And that was to head the way he came and to the left of the passageway. The others looked at him concerned. "Is he alright, Don?" he heard Mikey ask.
"I'm not sure." Don replied.
Leo ignored them to find himself standing in front of two doors. Both had pass codes. 'Right is bite, left is theft. What is up, that is down. Swift dragon's cross around.'
If this was another riddle, Leo wasn't buying it. The door to the to the right had weird markings on it while the left was bare. Then it dawned on him. The markings appeared like dragon flying around in what appeared to be the shape of a cross. Dragon's were evil and evil was wrong. Right wasn't the door they needed to take. And the whole 'Right is bite, left is theft' were passwords, hopefully. He grinned.
"Don, type in the password for the left door."
"Alright, Leo. If you say so." Don studied the pass code. After a moment, he typed in a password and the door opened. "We're in."
"What was the password?" Leo asked.
Don studied Leo for a moment. "Theft. Why?"
"No reason."
As they entered, the door closed. The room was pitch black for a moment, then lights kicked on. In front of them was something they didn't realize could exist.
