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.
Factual error: The Legends are stranded in England and wait for a bus to London. However, the bus that pulls up is left-hand drive, when it should be a right-hand drive one.
Jefferson 'Jax' Jackson: Is there anything you think about other than yourself?
Leonard Snart: Yes. Money.
