When Agnes DeMille asks Wednesday if she can sing at the funeral she mentions "Somewhere Over The Rainbow". The title of the well-known song from the movie The Wizard of Oz (1939) is "Over The Rainbow".
When Sheriff Santiago arrives at the Galpin house, she bursts through the front door with her gun drawn and immediately arrests Wednesday for murder. At this point, she has not entered the room where Donovan Galpin's body is seated facing away from the door, and therefore could not realistically have known he was dead.
When Wednesday is speaking to the chained Tyler, as the chains are pulled in and the shock collar activates, it can be seen that the chain attached to his right arm is attached with a cheap, non-locking carabiner that would barely hold any weight.
The driving instructor tells Wednesday to place her hands at 10 and 2 on the steering wheel to drive. This is an outdated technique, for two reasons, the first being power steering becoming standard negating the need for extra leverage turning the wheel. The second is due to the now standard airbag in the steering wheel, it is recommended hands are placed at 9 and 3 to lessen the risk of the airbag deployment causing injuries to the arms and hands being flung into the driver's face causing more injuries.
