Couldn't make the "This is why I love you" line fit in there, maybe I'll come back and fix it
"Please perform retina scan." A mechanical female voice said from a speaker. A green light shot out and skittered over the Straw Hat pirate's face.
Luffy took a step back. "Who's retina?"
"It's a what, not a who." Law said. He stood next to his ally and studied the lock door. He then looked over his shoulder at the scientist hiding in the corner.
"I'll never open it!" He shouted at them. He closed his eyes and clasped both hands over them.
Luffy gave him a quizzical look before turning to Law. "Can he open the door?"
Law nodded. "The light here," He waved his hand in front of the screen and speaker. "Scans over your eye and identifies the retina. It's programmed to open for specific ones." Luffy pointed toward the cowering scientist and Law nodded.
"Hey!" Luffy yelled. "Come open this door for us."
"I already said no." The scientist curled himself up in the corner still covering his eyes.
"Wait, can't you just take the eye? We don't actually need the rest of him, right?" Luffy asked.
Law grinned. "Yeah, that would be easier." He stepped toward the cowwering man who let out a terrified squeak.
"Don't worry, Torao's really good. He can put it back if you want." Luffy smiled.
A moment later, Law came back with the eye ball on a scalpel. He leaned down to place a kiss on Luffy's cheek. "I love you." He scanned the eye.
"Shishishi, Torao had fun, huh?"
Law nodded. "I suppose I should put this back..."
