- Etta worries for a second that Walter is going to ask her to sacrifice her bullet, she’s relieved when he only requires the chain. As we’ve discussed, the bullet may (or may not) be the one that Walter used to shoot Olivia, thus saving the universes, at the end of Season 4. Given the ongoing focus, it looks like we’ll find out its obvious significance to Etta in the upcoming episodes.
- Angel Device – second generation Observer tech, designed to prepare them for time-travel. The loyalists figured out a new way to use it. Etta uses it to torture Gael, ageing him, rapidly.
- This is of course reminiscent of the rapid ageing process from the second episode of Fringe — “The Same Old Story“
- Walter uses a pigs eye to mimic the pattern on Gael’s eye to get past the security scanner. This also draws some resemblance to “The Same Old Story“, where Walter was able to capture the last images from the eye of Christopher Penrose’s victim. Olivia also dreamed that she was pregnant in that episode.
- Another reflective image, but this one is different. Etta is standing behind the mirror, essentially concealing her emotions from projecting out in the world. This plays into her own changing internal landscape and the fact that she’s had to be very good at shielding her mind from the Observers.
- She does reflect, however, upon letting Gael live. She projects the positive side of her nature for her mother to see.
The final big projecting image is that of Walter from the past, moments before ambering the fail-safe message, inspiring himself and the team with hope..and a treasure hunt.
- Olivia and Peter were “caught in [the] blast”. Peter asks the paramedic, “where have they taken the kids?”
- Peter, Etta, Walter and now Olivia have all had significant dream/sleep moments in the opening two episodes. Etta’s is slightly different but still important in that her bullet necklace fell from her neck while she was asleep (5.01).
- Walter knew both Portuguese and Swedish.
- The team entering the lab was reminiscent of its introduction in the pilot. In truth, the lab has a sort of ongoing “origins” quality about it.
- Walter wonders where the term “in a pig’s eye” comes from. The phrase means you think there is no chance that something is true or that something will happen. This may play into the “DOUBT” glyph code from “Transilience”.
- The concept of the Fringe team having their own ‘eyes’ into Observer patrolled areas (courtesy of Gael) is interesting in itself.
- Walter’s tape (and the missing parts) resemble LOST’s Dharma Initiative orientation videos.
- Update: The Angel Device is also callback to the season four episode “Making Angels“, in which we learn about the Observers’ tech-based abilities.
- The glyph code for “In Absentia” spelled “FAITH“. (complete glyph translations).
