Audio problem: When Kendal is at the prison talking to Aaron, she says, "Impressive handle," but you can see her reflection in the glass and her mouth isn't moving.
Other mistake: Keith tells Veronica that Woody's password is "mrgoodwood." When she types it in, 11 characters are entered, but the password is only 10 characters long. It can't be a "." because Mac OS doesn't use that character in passwords.
Continuity mistake: When Veronica gets the SMS about Aaron's verdict, her hands switch around from being below to above the desk.
Visible crew/equipment: In the shot in the Mars apartment when Keith is going to answer the phone, a microphone is briefly visible in the upper right. (00:04:45)
Character mistake: Logan tells Heather that Mario Kart (Double Dash) has an online mode. It does not.
