I believe we already know him.

Think: YEN SID is an anagram for SIDNEY. He finally came back and Adam confirmed he will have an important plot throughout the next episodes. Also, we have two episodes with titles that seem to be related with him. Of course there other "glasses" and "mirrors" that might happen to be the focus of those episodes, but it's very probable we will se Sidney growing in the story... God knows how old he is! He might very well exist for centuries before Leopold found him on the beach.
