Next Episode Clue

A billboard in 'Anomaly XB-6783746' says "Smriti Isolation Tanks", foreshadowing Walter's use of the iconic sensory deprivation tank in 'The Boy Must Live'. The word "Smriti" is Sanskrit for "that which is remembered," and Walter went into the tank to help him extract a memory buried in his subconscious.

Walter called Astrid 'Acid'.


Captain Windmark:
"He is no child. He is a chromosomal mistake. A genetic anomaly. Designate progeny XB-6783746. Like all anomalies he was scheduled to be destroyed. But he went missing. It was a great mystery in my time. No one knew what became of him. Until now."
Nina Sharp (to Captain Windmark):
"Do you know why you tilt your head in that way? It's an involuntary reflex in your physiology. It changes the angle at which sound waves hit the eardrum, allowing in more stimuli. Like a lizard. I've studied them too. Intriguing characters. Their brains have evolved over 320 million years, yet for all their evolution, they form no bonds. Love does not exist for them. They are incapable of dreaming, of contemplating beauty, of knowing something greater than themselves... not unlike your kind. The experiments we conducted right here in this lab yielded a surprising result, because for all your years of evolution, you inadvertently redeveloped and honed primitive instincts that we moved beyond long ago. So in reality, you're the animal."

  • Captain Windmark (about Michael in "Anomaly XB-6783746"):
    "Like all anomalies, he was scheduled to be destroyed. But he went missing. It was a great mystery in my time. No one knew what became of him."

    Michael's disappearance in the future was a mystery, like Peter's disappearance in the Redverse.

    Fauxlivia (in "Over There (Part 2)"):
    "You know, when people find out that you're back... you're gonna be famous."
    "What do you mean?"
    "Well, your kidnapping. It's a famous story."
