The CW has become the defacto home for the bulk of DC Comics-based TV shows, having now added the CBS-originated Supergirl to its lineup. Supergirl and The CW's The Flash crossed over earlier this year, in turn establishing the former as being part of the multi-verse introduced in Flash season 2 - even before Supergirl made the moved over to The CW. That means Supergirl, The Flash, and Arrow are now all part of the same continuity.
Of course, there's also a fourth piece to the puzzle that is The CW's DC TV show multiverse: the time-hopping series Legends of Tomorrow. A newly-released behind the scenes image from the Legends set affirms that the show will continue to be the most off-beat part of the "Arrowverse" when it returns this fall for its second season.
The image, Tweeted by Legends of Tomorrow writer/producer Marc Guggenheim, shows Brandon Routh's Ray Palmer - aka "The Atom" - riding on horseback in full armor. The horse's riding equipment and a conspicuous Samurai helmet indicates that the scene being filmed here likely takes place during an upcoming sojourn by one or more of the Legends team to feudal Japan.

While often thought of as being a standard size-changing superhero akin to Marvel's Ant-Man, The Atom has typically been a more esoterically-inclined character in his comics history; so it's not too surprising to see him decked out in unusual threads for one exploit or another. In the comics, his ability to use size-changes to slip between dimensions or break the laws of relativity vis-a-vi time travel have led to him having adventures all over the chronological spectrum and even discovering (and becoming the champion of) "miniature" civilizations or even entirely seperate dimensions - occasionally at the risk of not being 100% certain if he has returned to the "correct" version of his own reality.
Left unsaid is any sort of context for the image or what the events depicted will mean for the running plot of the upcoming season. The Legends team's ability to move through time has made them central figures of the unfolding Multiverse concept, which is set to expand both in scope and importance over this next broadcast season. News of a four-way crossover event between the three established series and newcomer Supergirl has already been confirmed. The wrap-up to Legends' previous season left plenty of room open for newer and more elaborate adventures to come.
The Flash season 3 will premiere Tuesday October 4th at 8pm on The CW, Arrow season 5 will premiere in the same timeslot on Wednesday October 5th, Supergirl season 2 on Monday October 10th, and Legends of Tomorrow season 2 on Thursday October 13th.
