The truth of the matter was that Rey already had a discussion on the Elf issue with Rebal not too long ago.
It seemed the Elves were still around, and they were very much interested in the exchange.
Rey was personally going to see them and acquire more information about the Elves—as much as he possible could—while trying his best to form some kind of connection to them.
He would take things slow and easy until he knew enough before he suggested the idea to Esme.
'Who would have thought she would bring it up first…' He smiled wryly as he sat in his room.
Rey wasn't upset her decision. In fact, he understood it perfectly.
'Just the way I fight for humans, she probably wants to do the same with those she closely relates to the most.'
Besides, the Elves never hurt her like the humans had. They were also the more superiror race, and they would be able to help her grow a lot faster than the humans.
