Where did Jeb get his I'm-so-hip-man jargon from? Nobody else in Collinsport talks that way, and you can bet he didn't get it from Oberon or Haza.
That's a very good question. Maybe while the Leviathan creature was morphing in the room between phases, Megan let it watch '60s hippie/beach/teen movies on TV so it wouldn't feel so lonely and to help it pass the time.
If so, perhaps it's favorite was '65's
The Beach Girls And The Monster, which features a reptilian creature covered in seaweed - not all that different from the droppings we see the Leviathan creature itself leave behind.
And for all we know it identified with that creature and patterned it's entire method to woo Carolyn on that film.
Q has a strange vest.
As will become evident in subsequent eps, Q is wearing a gray topcoat over a gray suit (the "vest" is actually the suit's jacket
). Apparently TPTB decided gray would be one of Q's favorite colors of choice in the present. Apparently he was also way ahead of the coming men's monochromatic look of the past decade or so.
