Clark knew he had a twin, his pod had a message talking about them, but your pod didn't make it to earth, Clark thinks it might have been knocked off course like Kara's was, but instead of landing years after Clark, your pod likely landed on a different planet or... Clark didn't want to think about the possibility that no one found you, it's a thought far to dark to bear.

Clark went on with life, always feeling like birthdays were missing something, missing you, a twin he only saw in one picture on his pods data, that was until he and the JLA were dealing with Lobo in space one day, Lobo always talked about some 'friend' he had before, but this was thare first appearance, and its you, Clark can immediately tell by how similar you are to himself.

"Stop! Stop fighting, just..."

Clark halts the fight, the mission was just to rescue astronauts stuck on a planet and Lobo interrupted, now, you, his lost twin, stands by Lobo as he was knocked over.

"Let's just talk, ok?"

Clark raised his hands in a show of peace, he wanted to know what happened to you, why you are working with space mercs, if you even knew him.
