Left Behind - S1-E9
Plot hole: It's revealed that Chronos is Mick from the future after he was abandoned by Snart. However, in the episode White Knights (episode 4) the earlier version was able to sneak up on Chronos and surprise him with an attack from behind. If that was a future version of Mick then surely he would have remembered the attack coming and could not have been so easily caught off guard.
Out of Time - S2-E1
Other mistake: Sara tells Jefferson that the professor has a one hell of a right hook (referring to Martin knocking Einstein out). Jefferson replies, "seriously, Gray punched him out?" The subtitles mistakenly say "Ray."
Leonard Snart: This isn't my first prison break.
Trivia: When Zari says she'll agree if the team helps break her brother out of A.R.G.U.S., Rory replies "Prison break. I'm in" Dominic Purcell and Wentworth Miller (who play Rory and Snart) both stared in the TV show "Prison Break."
Chosen answer: Black Canary, Spartan, Wild Dog, and Ragman.
