Thitida, I'm with you on Rayek needing true love and a family. The vast majority of his problems have been caused by his consistently choosing achievement over community and connection. Problem is, he was too possessive of Leetah. But I think he's learned quite a bit since then.
Thinking of Recognition as something that just happens to an elf, is it possible that it won't happen if they want it too badly? I know certain events can trigger it (like having a conflict with your to-be-Recognized!), but does anyone think things like the internal stress of trying too hard for it might actually discourage it from happening? Look how Rayek tried to force it with Leetah.
Maybe he'd Recognize someday if he'd just let things come naturally.
