Captain Eko, a Light Spren?

It's been suspected that timber is the daughter of captain eko, who fairies the gang in shadesmare. He has a comment that his daughter used to work at a particular shop, until she ran off chasing stupid dreams. So we assume that spren don't like wen their other ther siblines, er daughters, or whatever, run off to the physical realm. That would be the reamponding with a human. But while early n this relationship is just a kind of protection thing,. i guess for now, this eventually turns into a nice, radiant situation, right? Yes?
