Everyone knows that Ace is paranoid about people discovering his father's identity. Now he was applying his very reasonable paranoia to Locks. While he would gladly make use of her unique powers to terrify people, he was determined that those people wouldn't realise what she was. He made both Locks and Luffy put cloaks on, wearing one himself as well. He and Luffy grinned at each other. Look out everybody, here they come.
oOo
The people didn't particularly pay much attention to three small cloaked figures skulking in the alleyways. At least, not until Ace spray painted flames onto the walls. That's how the fun started. Paint is flammable after all. As the guards began to give chase, Ace gave the order. For a moment, Locks was running backwards. Then the spray-painted flames set themselves on fire. Man, did that give the guards a fright. The men stopped to stare at the fiery wall while the three made their escape to another part of town.
They next decided that an early lunch was in order. They raced through the market-place, snatching all the food they could carry before racing away from the fresh batch of guards. Through some miracle of physics, the three squeezed into a barrel and ploughed through their snacks. Ace and Luffy did, at least. Locks didn't really eat much between meals.
They returned to the original scene of the crime, trying their flame trick on the next rotation of guards. The looks on their faces!
Luffy had glue and glitter, though no one dared ask him why. But they were sure to put them to good use. First they sent Luffy running through with the glue, squirting it everywhere. Then Ace sent Locks running through throwing glitter. She seemed mystified by the instruction. Ace watched to make sure neither got caught, but mostly so he could see the expressions on everyone's faces. Priceless.
oOo
After a lunch of stolen sausages (fire breathing girls were very useful), they moved on to a more shady part of town. Locks seemed to enjoy their exploits here more than she had earlier.
First, they descended on a batch of thugs that couldn't take the hint that Locks wanted nothing to do with them. Finally, the girl lost her temper. Ace laughed his head off as they met his dragon (and her lightning). Wait, his dragon?
Then Luffy demanded an after lunch snack (Ace was inclined to agree). Things certainly got interesting when the waiter tried to make Locks pay for the meal. She had chosen to calmly walk away instead of racing the boys. The waiter would be scarred for life (mentally) after Locks showed what Ace thought was a surprising command of curses. She also set the table on fire, put the fire out and electrocuted three other staff who attempted to prevent her leaving. Was it just him, or did she electrocute everyone. Let's not forget how she made a glass full of water fly into the manager's face, yet another ability Ace hadn't known about. The brothers laughed at all this from behind the safety of a stack of crates.
oOo
After oh so casually leaving, Luffy somehow convinced them to visit Fuchsia.
"Makino!"
The rubber boy raced towards the green-haired woman as soon as they entered Party's bar. Ace lingered near the doorway, unnoticed by any of the bar's occupants. He motioned for Locks to go forward, though. The girl did so hesitantly, seeming uncomfortable around the few people in the bar at this time of day. Makino smiled.
"Who's your friend, Luffy?" she asked. Locks shrank back, slinking to Ace's side.
"That's Locks!" Luffy said cheerily, but he made no mention of dragons thanks to a lecture (*cough* thumping*cough*) Ace had given him a few days ago.
They spent their visit stuffing their faces, and introducing Locks. The girl didn't like getting close to other people, something that Ace had never noticed before. It took them an hour to get Locks to stand still long enough for Makino to say hello without fear of electrocution. Makino didn't seem to mind, though, just smiling each time the girl growled at her.
Ace was grateful that Makino was so patient, because he was pretty sure he would have given up if he was in her shoes. He did note, however, that Locks was gentler with her electricity than she had been when Ace had chucked her in the stream. He cringed involuntarily at the reminder.
oOo
They went home with full stomachs and a sleepy dragon and little brother. Ace "encouraged" them into the treehouse (Locks would have slept on the ground if he'd let her). The sun went down, the end of another eventful day.
