When Orsina drops Bradley the second time and can't find him, she will ask for your help again.

Compared to the first "lost Bradley" instance, this task is a lot easier, as you can easily find him inside one of Orsina's caves near the cooking station.

The funny twist with this task is that you can find Bradley sitting on the cave's ground close to Orsina's feet. Maybe Orsina just wanted you to visit her and catch up on each other.
