About halfway through this episode (1.4), the two "Tickets" signs become fully illuminated. Before, both "Ks" were out as was a "T" on the left hand sign. All globes in the signs are only illuminated for one scene - in all following scenes, they revert to their partially illuminated states.
Early in the episode, both of the "Tickets" signs were broken or incomplete. When revisiting the arcade, the "Tickets" sign is whole.
When Elliot and Mr Robot go to the drug house - the person out front says that only Elliot can go in, that Mr Robot has to wait outside. Shouldn't Mr Robot just be a figment of Elliot's imagination?
The crew is stealing a minivan with bumper stickers from a mother in a New York City neighborhood. The van appears to belong to the family. However, when they link up the computer in the van the Air Conditioning has "No Smoking" stickers on it, which is generally only placed in rental vans. This likely indicates that they used a rental van for filming and added bumper stickers to make the van seem more like a family's.
When Elliot is changing his drug screen report, Marijuana is misspelled as "Marrijuana".
Alderson kept mispronouncing 'daemon': It's an old spelling of demon (the 'a' and 'e' would be joined in a ligature) and should be pronounced as though the 'a' was missing.
