Previous Episode Clue

A logo and symbol for Trevisanus Bros Estimators are briefly seen in on the side of a van in 'The Dreamscape' as Olivia and Charlie chase down George Morales. This same logo and symbol are seen on the side of a van (possibly the same van) in 'Safe' as Loeb and his crew prepare to receive David Robert Jones at Little Hill Field.

Next Episode Clue

There is a poster for 'The Colds' on the bar wall behind Olivia in 'Safe' when Peter shows her a card trick. This is a reference to the supersized common cold virus in 'Bound'

Next episode clue


  • The locations of the safety deposit boxes are known by Jones, given to Loeb.
  • Jones told his lawyer to go to his personal tailor so the tailor could fix the lawyer's suit up for Jones.



  • The safety deposit boxes were all purchased 23 years ago. (Lost)
  • Charlie said the villains landed in Providence "47 minutes ago." (J.J.)

Walter asked to go out for breakfast.


- Project 1069 - Exploration 1 -

The Transcendentalists had the right idea, they merely lacked the technological tools. How did Ralph Waldo put it? Oh yes;

Nature shows all things formed and bound. The intellect pierces the form, overleaps the wall, detects intrinsic likeness between remote things, and reduces all things into a few principles.

Or in this case, a few particles. Yet those particles fill less than one percent of the space within the atom, virtually all of it contained within the nucleus. The protons and neutrons themselves consist mostly of space between their constituent up and down quarks. Subatomic vibration (of an origin that I cannot fathom) could in principle disturb the energy fields between, allowing the penetration of other particles through the open doors. To break on through to the other side!

Yet just as some small fraction of Rutherford's electrons failed to pierce the gold foil and bounced back instead, some fraction of the particles within the perpetrators' atoms must have collided with particles in the wall -- resulting, of course, in the release of ionizing radiation! It is perfectly obvious, upon reflection: "Space is ample, east and west, But two cannot go abreast." Although that well-endowed Baltimorean woman might beg to differ. Harmony of the spheres, indeed! Pythagoras, you dog.

- Cleveland: homeless man with superfluous nipple hidden beneath his grimy coat
- Baltimore: idle ditty whistled by street vendor, every D was just a little flat
- Philadelphia: fabulous crusty cheesesteak sandwich at Beach and Palmer

So many details, yet none that actually matter! Where oh where have my details gone? Lost -- or stolen. I asked the Summoner if I could search for my errant thoughts in his lost & found, but he refused, said I'd find the missing friars in Satan's hindquarters. Curse him! I know the rule: "cannot build phallic puzzles inside the lab." I still know the numbers, too -- well I damn well should, it's a simple second-order recursive algorithm -- but a mnemonic is worthless without its contents. Like a sad coat rack with empty pegs.

Connection chart: Safe


S1E01 - Pilot

  • Olivia (in "Pilot"):
    "[Walter worked on] things like mind control, teleportation, astral projection. Invisibility, genetic mutation, re-animation, fertility..."

    In "Safe" David Robert Jones was teleported out of prison using equipment retrieved from Walter's safety deposit boxes.


S1E02 - The Same Old Story

  • Walter (in "The Same Old Story"):
    "You have no idea where I've hidden things!"

    In "Safe" the Fringe team learns that Walter has hid pieces of a machine in safety deposit boxes around New England.

  • Walter (in "The Same Old Story"):
    "It's one of the inherent pitfalls of being a scientist. Trying to maintain that distinction between God's domain and our own. Sometimes I forget myself, but then you already know that. If you've read my file then you know the truth about Peter's medical history."

    Walter elaborates on Peter's medical history in "Safe" when he discusses the device he made to help save Peter which the villains try to steal to free David Robert Jones.

  • Massive Dynamic Technician (in "Safe"):
    "We managed to resolve the last image in Agent Scott's optic nerve before he died."

    This is the same technique Walter used on one of the victims in "The Same Old Story".


S1E07 - In Which We Meet Mr. Jones

  • Jones asks the cryptic question "Where does the gentleman live?" in "In Which We Meet Mr. Jones", to which the answer is "Little Hill". Jones is teleported out of prison to an abandoned airstrip called Little Hill Field in "Safe".

S1E08 - The Equation

  • The mathematical equation completed in "The Equation" is used vibrate matter in a way that lets objects effectively move through walls, as seen in "Safe".

S2E15 - Peter

  • Peter flipped a coin through his fingers in "Safe" like both Peters did when they were near death in bed in "Peter". (Image 1, 2)
  • Peter (in "Safe"):
    "What's with all the toys?"
    "They're your toys, son! From when you were a little boy."
    "Those aren't mine."

    They belonged to the Peter that died in "Peter".

  • Walter (in "Safe"):
    "I was under a great deal of stress at the time!"

    Walter was stressed when he hid the pieces of the machine in safety deposit boxes 23 years earlier. This episode takes place in 2008, so 23 years earlier was 1985, the year Peter died in "Peter".

  • In "Safe" Walter said that Peter miraculously and spontaneously started to recover from his bird flu. In truth, Walter's Peter died in "Peter", and Walter stole the other Peter.

S2E18 - The Man from the Other Side

  • Jones needed to use a decompression chamber after teleporting to Little Hill Field in "Safe". Mr. Secretary needed to do the same after crossing worlds in "The Man from the Other Side".

S3E05 - Amber 31422

  • Matthew and Joshua Rose were robbing banks in "Amber 31422" by weakening the molecular structure of the bank walls, the same technique used by Loeb in "Safe".

S3E08 - Entrada

  • Walter (in "Entrada"):
    "No. I remember why this is familiar. They're harmonic rods. Like Belly and I used to use to help objects cross between universes."

    The teleportation destination for David Robert Jones in "Safe" was anchored by harmonic rods, which are often used as tools used in crossing over as seen in "Entrada" when harmonic rods implanted in Fauxlivia help bring her back to her universe. (Image 1)
