We had another sideshow case of the week on "A Better Human Being." I understand the need to continue cases, because they are an FBI task force after all, but they never fully meet the overarching story of our characters, where they were and who they have become. You'll get a mention of the case here and there in this review, but you won't miss anything as I gloss it over.

The change in Walter continues, as he just naturally leaves the lab for investigations. Nobody seems to even notice anymore that he's not frightened of his own shadow. With Peter here, he is a different man. This man also has a fatherly instinct, and that tells him that his son is somehow forcing his own memories onto Olivia in a desperate need to get "his" Olivia back.

He was just blindly tossing out ideas, like empathy, and Olivia sat there with a serene look on her face, knowing deep in her heart that whatever she was feeling was true.

I mentioned last week that I think Walter is experiencing memories of his own of his life with Peter, but they are different. It's more of an emotional and philosophical bond with him that propagates itself in his actions. It's much easier to overlook than Olivia remembering everything that happened with Peter's Olivia in his world.

As confusing as it is, this world, I believe, is the world that remained after Peter was erased. Thus, the same timeline without Peter in it. Since he forced himself back into it, he brought with him all that he influenced from the time he died until the time he was erased. How I wish I had a scientific mind, because the idea of quantum physics and trying to figure this out makes me all aflutter.

Is it a coincidence that I mentioned "6B" last week and Olivia remembered it this week? I don't think so. I believe Fringe is trying to get us to think outside the box. Or, inside one of the many boxes they've already created. The steps to where they are taking us have been set and it's like pieces of a puzzle waiting to be put together. I'm sure you won't be surprised to learn I can get vexed at puzzles and try to force pieces in where they have no business being.

When our dynamic duo was at the storage facility and Olivia said she wasn't scared and Peter realized he couldn't be projecting his memories onto Olivia, did anyone else expect the storage locker to explode? I had my hands on my face, my mouth in the shape of a big O, similar to that of the dead dad of 200 genetically-altered mutants.

I wish that had been it. It would have been so much easier to forgive than Alt-Nina kidnapping her. I had to go back and revisit several episodes to determine where the never-before-seen Alt-Nina took over our Nina. I think she was already gone in "Forced Perspective." She was trying to take her gloves off when she got to Olivia's place, and offered to give her the medication for her migraines. That one is easy. Additionally, the Observer was watching, so he knew Olivia was in trouble.

However, in "Wallflower," it was the first time we ever saw Nina not quite understanding about Olivia's past and what she had been through with the Cortexiphan trials. So where did things start to fall apart in this episode? My first thought was at the "A-Ha!" moment Walter had about Nina when he asked Lincoln to take him to the bridge to see Nina. Why did Walter have to go to the bridge in order to see Nina? Somehow I completely missed that she had moved her office to the link between our universes.

Immediately I noticed that she was wearing open fingered gloves. Our Nina never wore those, because of her metallic hand. I double checked to ensure that in this new timeline perhaps she didn't have the shape shifter skin covering her hand, but in all real Nina scenes, she wore two gloves.

The vault was bio-metrically secure, with her using her left hand. They showed the right, skin up wearing a ring. I'm sorry that I lost faith in Nina and thought ill of her, that she might be working with David Robert Jones and Broyles. She looked quite disheveled. Who knows how long she has been held captive?

There is nothing about this season that is a letdown. The scene between Olivia and Peter in the car at the gas station was classic material. A die-hard fan could not complain and even a new one had to be moved by their exchange. I am more ready for next week than I have a right to be. Give me more Fringe!
