Flint replied to her, "Well let's just say I'm good with children. Someone has to, after all, anyway thanks for the save. Come along Scruffy."  He didn't know nor really care how this animal got aboard. This would be something to take care of later once things calmed down. Eventually he'd see the dragon, the Cap, and some more new faces coming aboard. It seemed like it was starting to get a bit crowded on this ship with all the people. This might be something he would broach to the captain, he did have plenty on money on hand give or take what would be used on supplies.  

"Hey there Cap' here's Scruffy. I hope you like him as there's not taking him back." He said to her as he took a sip of drink from his canteen. He took another as he felt himself refresh after the events that transpired earlier. During that time Alesia gave the orders to set sail for Loguetown. It seems like they'd finally be entering the Grand Line. He wasn't surprised, it was bound to happen. Things would get more interesting once they leave Loguetown. 

"Cap' when we get to Loguetown mind if I chat with you about some things?" He said to her before he went off to work. He'd assist in the sailing of the ship. Well as much as he could anyway, with all the new people on it's not like there would be dearth of tasks to be done. After they were set for their destination, he would go back to idling and watching everyone move around. He leaned against the mast and adjusted his shades. He thought about the Mayor's instructions. Hopefully he'd steer clear of any distractions and be able to do this task.
