- The concept of wish-fulfillment is one that runs throughout Fringe..
- It continues in season 5 from the first very frame with young Etta making a wish from the dandelion pod. She might not have known it at the time but it’s symbolic of her desire to find her parents, a wish that is fulfilled once she’s reunited with Olivia.
- That this wish is replayed inside Peter’s mind adds an extra layer of intrigue and emphasises his own burning need to find Etta.
WHO KNEW OBSERVERS BLUE
- The famed blue lights scorch the earth as the Observers penetrate our universe — we’ve seen them pass through dimensions before but this was no making angels.
- The blue lights/flares have largely been used as universe signifies, though in the first season they had a different, more observational quality to them.
HANG AROUND YOU’LL SEE HER AGAIN
- Etta instinctively reaches for her bullet necklace (as first seen in “Letters of Transit“), which is likely the one Walter used to save the worlds by shooting Olivia, but notices it has fallen from her neck overnight. Just one of several mystical indicators throughout the episode and a sign that she’ll soon find her mother.
- Those signs continue with Walter next to receive a message from the ‘cosmos’. He wakes to light dancing across a wall, symbolic of his own barriers, beckoning him to come down from his window above (and reminiscent of Bellie’s SOS in Lysergic Acid Diethylamide).
- Curious, Walter peers through the blinds that further symbolise his blinkered perspective and partitioned state of mind, but is unable to see the possible meaning in the message just yet.
- But the signal has left an impression on him, and as we’ve seen throughout the story, often messages recur to take effect.
EGGS STICKS, RED VINES SWING
- In 2036, Egg Sticks (aka “punishment food) are all the rage — though, as Walter discovers to his cost, they’re certainly no substitute for delicious delicious Red Vines.
- The word “HOPE” can be seen backwards (from our point-of-view) on the scrabble screen. Hope is of course a prominent theme throughout the episode, as is perspective. By the end of the episode, Walter seems to have regained both, as foreshadowed here.
THE GLYPH HANGER
- Butterflies on the walls — a nod to the famed Fringe butterfly glyph.
- The last time Walter spoke to Olivia before they were ambered she was in Columbus Circle. According to Wiki, Columbus Circle is the point from which all official distances from New York City are measured, which is fitting given that Olivia is the center of the story, the one who holds the family unit together. It’s also fitting that there’s a clock in the graffiti.
