Fan Translation:
A return gift from Cu Chulainn (Alter).
A doll you're certain to have seen somewhere before. By the way, you tried asking Medb, but she said she had absolutely no idea, or something along those lines.
When you put it by your bedside, you'll find it elsewhere when you wake, at times showing up with new wounds. When that happens, why not help it out by stuffing more cotton and sewing it up.
