A small, cartoon bird is seen in Chinatown when Fauxlivia escapes captivity in 'Bloodline'. Broyles sees this same bird in 'Lysergic Acid Diethylamide' during his LSD trip.
A poster in Olivia's mind in 'Lysergic Acid Diethylamide' that says "Be Vortex Aware" foreshadows the vortex that consumed part of a ranch in '6:02 AM EST'.
PETER: "Who is this guy? I saw him in your mind. You had him locked up in a zeppelin, he was just flyin' around trapped in there."
OLIVIA: "Yeah, I don't know, I haven't seen him before. But I think that he's the man who's gonna kill me."
