Narrative:

We landed at ZZZ. Once the passengers deplaned and headed on their way I informed the line personnel that we were a quick turn and needed a ground power unit (gpu) and fuel. We then proceeded to clean and restock the airplane prior to our empty relocation flight. When we completed all those tasks I decided to get the fuel panel set up for our fuel upload and perform a post flight inspection. I noticed as I approached the fuel panel from a distance that there were several large dents in the leading edge of the starboard wing. I then inquired with the second in commend (sic) to see if he had seen the damage on the wing. His reply was that he had seen it and even noticed the damage during his final walk around prior to our departure.leading up the event:leg 1.we do not know when the damaged occurred to the leading edge of wing. I had to fly the aircraft single pilot to ZZZ to get in place for an early departure out of ZZZ. I had the aircraft fueled at [at departure airport] prior to completing the preflight inspection. I did a very thorough preflight that morning while it was still dark utilizing the D cell flash aboard the aircraft and the surrounding ramp lights. I did not notice any damage to the aircraft at the time or during my final walk around just prior to departing. Leg 2.upon landing at ZZZ I advised the ground crew that I would need a fuel truck and gpu. At that time the sic walked out to the aircraft and we discussed details regarding the flight and what need to be completed prior to our departure from ZZZ. The sun had just started coming above the horizon at this point and began providing some light to the ramp area. I again stayed aboard the aircraft while the sic went inside to grab some stock items. The fuelers began to fuel the airplane while I prepped [for] departure. The sic came back and while the fuelers were still fueling we started going through the before start checklist together. Upon reading 'fuel quantity?' I noticed that the fuelers had just fueled past the requested fuel load amount and continued fueling so the sic went out to stop them. When he came back up front we completed the before start checklist and before heading inside I checked the fuel panel to ensure all switches were off and guarded and the door was securely latched. We waited for all the passenger to arrive for about 15 minutes and headed out for departure. While the sic helped the passenger load up I completed the final walk around. At no point during our time on the ramp did myself; the sic; the fuelers; or other personnel notice any damage to aircraft. The damage that occurred did not appear to be from a bird or wildlife strike of any kind because there was not other evidence (blood; feathers; fur; or other damage to the airplane) to suggest that an animal had been hit. Leg 3.we had arrived at ZZZ1 just after lunch and elected to not get a gpu because the airplane would have had to been moved to accommodate it. One passenger had already showed up at the airport so I began prepping the airplane for departure as far as I could without continuous power to the aircraft. As I finished up what I could; the sic was finishing refreshing the coffee and ice and was informed that all the remaining passengers had just arrived. We agreed that I would stay aboard the aircraft to turn on the batteries and continue prepping the aircraft while he greeted and brought the passenger out to the airplane. While the passengers were boarding the sic completed the final walk around inspection and removed the wheel chocks from the nose wheel. Once he completed the walk around he boarded the airplane closed the door and briefed the passenger on the upcoming flight back to ZZZ. He climbed upfront as I finished the prepping the airplane and once we were both strapped in we completed the entire before start checklist. When asked why he didn't inform me at ZZZ1; his response was that he assumed I had seen it already initially; but alsomentioned that he forgot to bring it up after he boarded the airplane.
