This episode's glyphs spell:
Olivia tried to escape from the Redverse back to the Blueverse by breaking into the Liberty Island facility and using the sensory deprivation tank.
The Observer can be seen outside the diner where Olivia and Henry meet.
The skull and crossbones chatroom icon in "6955 kHz" foreshadows the abduction of Max, who had a skull and crossbones flag in his room, in "The Abducted." Also, the chatroom's emphasis on the word "TEAMWORK" foreshadows the reveal that the child abductions are actually the work of two men, not just one.
A sign outside of Astoria Holy Witness Church in 'The Abducted' says "He That Enters Here Shall Be SAVED!". The bond formed between Olivia and Alt Broyles while working this case is ultimately what saves Olivia from death and allows her to return to her universe in 'Entrada'.
