Aksinya dodges all of the bad luck that happens to people around her because she's actually the source of the bad luck. Her parents offended a cleric when they were pregnant with her, and the curse has followed her around since. It doesn't always come up, it waits for the right time and then springs. The broken glass flowers are pure coincidence. The other campers showing up at this island? Aksinya. The strange nighttime sightings? Aksinya. All the horrible shit that's going to happen over the next few weeks?
It's all Aksinya, and she knows it. Watch her moves carefully. She's like an ambient WMD.
