I've been wondering about Eureka(spoiler from ep30+)
Spoiler:
She is a coralian but is very much human as any other person, biologically and becoming emotionally. Yet her hair and eyebrows aren't growing back, and her scar hasn't healed like normal people. She is like a living doll; she doesn't change, nor age. What is the significance of the collar that she and Anemone wear? Is that what helps them keep their form(will they turn into pudding when it's removed or something
).
