She loved you more than anything. She will know you even though you were young when she was taken.

[Because the thought of his wife not being reembodied is not something Thranduil cares to think about. He knows what if she was able to depart the Halls, she would choose to have the chance to see him and Legolas once more. It was a selfish desire, he missed her even if he never let it show after her death.

Thranduil was silent for a moment before he set his wine glass down. He gestured for Legolas to stay where he was while he went into his inner chambers to retrieve a small box. It was not something he had ever shown anyone, not even Legolas but tonight, he believed it was time. The box was handed to Legolas carefully before he sat back down, inside was a ring, perfectly fitted with a brilliant bright blue stone in a silver band.]

She will recognize this at least.
