You once rescued a stranded baby killer whale.
It sounds a bit suspicious of taking credit. After all, even a killer whale calf is too big for three or two humans to save, but you were the first to discover it and quickly called for help. During the whole process, it grunted uneasily, but looked at you dependently, so you should be regarded as the biggest contributor.
You have not returned to that sea area in the past few years, but the little killer whale often comes. It is bold and affectionate. The little guy who comes to the door greatly facilitates the observers. Follow-up observers have shared some information, because killer whales are social creatures. However, after several years of observation, this solitary little killer whale has no group or companions. It is unknown what its group has experienced. Fortunately, even without the mother's nurturing, it has grown up without any danger.
What they don't know is that killer whales also have a voyeuristic nature. People observe it, and it also observes humans. That stranding may have been its adventure. The second year after you left that sea area, the smartest little creature in the ocean learned human language. The fifth year after you left that sea area, it learned to change its shape.
Intention: A momentary act of kindness leads to unexpected gains.
