What a fun episode! Bellivia has been around long enough to be far less annoying, and more funny. Everything about this episode was enjoyable. Much of it comes from the mind of Olivia, via LSD she, Peter and Walter took to try to find her in Bellivia's subconscious.

Hey, it's Fringe, when they were discussing it I was willing to accept anything!

What an amazing way to brig back Olivia's stepfather. Because he hasn't aged in Olivia's mind, he can be the same actor. I absolutely loved that Olivia felt trapped in the first place she visited in the other world, The Twin Towers. For the rest of my life, I will always remember the Season One finale. A masterpiece!

"Lysergic Acid Diethylamide", however, wasn't being honest with us. That ornery Belly was the one they found. And from there they became cartoons. Cartoons!

It's easy to see why there were no promo pics for this episode. It was just too good to let it leak out ahead of time. There are times for spoilers, and there are times when the journey of watching live is part of the fun. This was one of those times.

Broyles touched the LSD, and it gave Lance Reddick some absolutely stunning material to work with. His entire persona changed. From the first diatribe about the mysteries of licorice to asking Astrid to hold his hand, he made the very best of the material he was given, literally transforming the usually stoic man.

Olivia's mind was a puzzle made from pieces of both worlds and horror movies and so much more. While our heroes were standing in New York City on top of the World Trade Center, I couldn't help but think that it was going to take weeks for them to get to Jacksonville, even if it's only in her mind.

How fast would a Zeppelin travel? It seems to be the method of travel in the other universe, so they must have a lot of time for traveling.

Much like the theory in the movie "Inception," if you die while on the LSD trip, you are out of the mission. That's a much better result than actually dying, like has been purported in actual dream life. Neither Walter nor Peter made it to the final scene of Olivia's trip, but I think the results would have been different if they had.

I felt like I was watching a superhero when little cartoon Olivia stopped her stepfather and an army of those trying to capture she and Belly with a raise of her hand, saying, "Stop - I'm not afraid of you any more." From there she became the adult Olivia, looking stunning and strong. Bell knew all along that his experiment to save both himself and Olivia wouldn't work, and he left his life for hers.

From his sacrifice, an energetic, tenacious Olivia was born. Her character will never be the same. Peter noticed she had drawn one of the men he encountered in the cartoon and asked who he was. "I don't know, but I think he's going to kill me," Olivia said, without a care for anything but to enjoy her snack and Peter's company.

As she chomped on a piece of toast, she let it be known that from now on, she is a force to be reckoned with.
