It's going to be hard finding a dark-haired green-eyed teenager that fits the bill, but maybe Annabeth will have an idea. [Even while he's talking he's taking her hand and bringing it up to eye level to examine the bracelet. He's leaving the journal on the table, too, as his fingers turn the bracelet in a circle to look at the links carefully.]

...I think I kind of remember something like this, too. In that memory with Annabeth in the alley. I didn't think anything of it since I was a little more weirded out by whatever I promised her, but if she got her knife back maybe they sent memory items out in a bulk package. Question now is why would you have a bracelet like this when we were kids?
