1 continuity mistake in The Climb - chronological order
Starring: Katie Cassidy, David Ramsey, Stephen Amell, Colin Donnell, Emily Bett Rickards
Factual error: There is no way Laurel Lance would have been allowed on the prosecution team for Moira Queen's murder trial. Due to the facts that she both dated and as a lawyer represented the defendant's son, the defendant's daughter used to intern for her, and her boyfriend was one of the people killed in the Glades, it would have taken all of two seconds for the court to have her removed if she didn't willingly recuse herself, since her presence would be a major conflict of interest.

Oliver Queen: I'm having some trouble with my computer and they told me you were the person to come and see. I was at my coffeeshop surfing the web and I spilt a latte on it.
Felicity Smoak: Really?
Oliver Queen: Yeah.
Felicity Smoak: Because these look like bulletholes.
Oliver Queen: My coffeeshop is in a bad neighbourhood.
Trivia: Although Laurel is a couple of years older than Sara, Katie Cassidy is only about a month older than Caity Lotz.
