The CW has released a preview for “It’s a Mad, Mad, Mad, Mad Scientist”, the upcoming fifth episode of DC’s Legends of Tomorrow’s seventh season. The episode will air on Wednesday, November 10th. With the Waverider having been mysteriously blown up by another Waverider at the end of Season 6, the Legends have been trapped in the 1920s, and in the upcoming episode, they will travel to New York City to track down Dr. Gwyn Davies, a scientist they believe will be able to get them back to their timeline. However, Davies isn’t exactly who they expect him to be, and, more than that, some of the Legends don’t necessarily want the team using Davies’ time machine at all. The episode will see the official introduction of Davies, played by Matt Ryan who previously starred as John Constantine on the series. It was announced back in July that Constantine would be exiting the series with Ryan staying on to play the brand new character, Davies.
