As a young man, I always liked The Visitor. As a grown man with a father and a child and a great relationship, with both, I absolutely LOVE The Visitor. Its one of the few shows that will move me to tears.

I don't think Superman would be asking Krypto to take him home - presumably the Fortress of Solitude being home - if Lex was in the Arctic or already found it. That wouldn't be safe or smart.
