This episode was a good one to come back from break on.
Chloe's return and the virtual world were very cool. Loved seeing her with powers.
Liked how Clark had a difficult time trusting Chloe after she had been gone and Dinah had a hard time as well.
Thought it was funny how Courtney and the others just disappeared between eps. >_>
Now that Clark knows he can fly, it could feel like a long wait until he does for real (If we do have to wait for it in the last episode).
Nice appetizer and I can't wait for the main course -- Lionel, Lex clone and -- Martha!
