Leo was, naturally, Lex. He simply took off his Host Attire and put on one of the glasses to stay anonymous. He still did not use his actual name though, to avoid even the chance of any suspicion.
He was excited because he had finally figured out a way to interact with his guests without having to worry about how he appears. He could ask the stupidest questions - after all, he was just the owner of a gaming shop. It wasn't even magical, like the barber shop or the Battle Ax. It was straight up video games on computers. It was unfortunate that he couldn't connect the shop to the Internet back on Earth but he could make do.
