Behind the scenes

  • The Latin "quid pro quo" is often rendered into English as "tit for tat" or "something for something", although the former has a greater sense of retribution, whereas the Latin merely declares the exchange.
  • King Arthur and Merlin are first mentioned in the shared multiverse, prior to them appearing in flesh in DC's Legends of Tomorrow.
