This was an extremely fascinating episoe for me, as it was full of great moments, that may play a significant role in the future, particularly in the exciting season finale next week.
I found the episode to be extremely and intensely funny, especially with Amanda, and her quote about Betty as the queen of the mole people! I was laughing so hard at that one!
The storylines were all very interesting, and there were some very unexpected twists (thus, the title being 'Curveball') and that really made it highly interesting and very entertaining.
Overall, I would highly recommend this episode, as it had all the aspects of a thriller and and amazing episode. Keep it up, Ugly Betty, as this is going amazingly!
