Eclipse + USMC-1856707 + Step Potential + Chain Lock + Ma - S5-E3
Character mistake: MacGyver is explaining the jamming of a tracking signal. He states that the tracking device is emitting an RIDF signal. He should have said an RFID signal. (00:26:20)
The King of the Delta Blues - S2-E6
Character mistake: "Are you going to send in the calvary?" is said twice. It should be "cavalry". (00:09:40)
Character mistake: After Ray Palmer says he's an Eagle Scout, he says to Leonard Snart, "be helpful to others, scout's motto." The Boy Scout's motto (including Eagle Scouts) is "Be Prepared." "To help others at all times" is part of the Scout's oath, but that's different than its motto and not something an Eagle Scout would mix up.
Suggested correction: It was a joke, that applied to the situation. Wasn't meant to be literal.
There is zero indication of any joke, implied or otherwise, especially since he could have correctly said "oath."
