-         Joey Paulsen is very briefly seen in the Bookhouse. The other Bookhouse Boy is Cappy, who we see eps. later assisting Mj. Briggs on his work with the petroglyph.
-         A picture with two owls in Truman’s office.
-         Jean Renault’s mugshot is clearly different than the rest, which are probably real. Check the numbers and how the other photos look much older…
-         The way Mr. Brockman, the insurance agent, touches Leo’s shoulder when he leaves.
-         Roots or branches in the Bookhouse ceiling and what looks like a tree (??) in the background. Chopping wood inside?!
-         It looks like Audrey is cursing to herself just before she says to Ben she’d like Coop to take her home.
-         Nadine carries some bags and a dress she just bought with the logo of Horne’s and the label “Junior Miss Department”. The script mentions this and it’s barely seen onscreen. Nice touch…
-         Ed, meanwhile, is fixing something. Fixing engines inside?! Yeah, you know Ed…
-         The spot by the lake where Maddy and James talk look exactly like the one seen in ep.1 where Laura gave James the necklace.
-         The cake for Leo reads, obviously, “Welcome home Leo”.
-         A couple of African men, dressed like... yeah, African men, seen when Leland is singing.
-         Trudy cracking her knuckles right after Leland ends singing and she begins a new piece.
-         When he’s talking to Tojamura Pete wears in his hat what looks like a four-leaf clover.

I believe Cappy is also the one who gets his skull cracked when that woman sneaks in to kill Truman.

Leo's wheelchair looks like an actual kitchen table chair transformed into a wheelchair

What caused Gordon Cole to lose his hearing? (he said it's a long story)

Slowed down Dance of the Dream Man plays again

Aside from his possession by BOB, was Leland a crooked lawyer to begin with?

Trudy plays Josie and Truman's theme on the piano

When the One Armed Man answers where BOB is from with "that cannot be revealed", it's another indication that the One Armed Man is not a good spirit but merely trying to thwart BOB

The One Armed Man says BOB has been near for nearly 40 years, that leads me to believe he has inhabited Leland for that long and Leland probably has a much darker backstory than we even know prior to the murder of Teresa Banks
