Hi, Greg! I have a few YJ questions.
1 - How does Mr. freeze sleep at night? Does he put a pillow in his dome? Does he freeze one in out of ice? Does he have a special freezer cell?
2 - When did Killer Frost become a villain?
3 - Did the Kroloteans Miss Martian blanked ever get better? The one Martian Manhunter was interrogating seemed decent enough.
4 - What is the nature of the Greek gods on Earth-16? Its been established they exist, but are they actual gods or 'just' powerful entities, like the New Gods?
5 - How did Doctor Fate react to Wally's death? Kent Nelson stuck around.
