Is There a Robin Easter Egg In the Legends of Tomorrow Trailer?

When the Legends head to P.T. Barnum's circus on an upcoming episode of DC's Legends of Tomorrow, it looks like they will be keeping company with one of the DC Universe's most famous families.

Like many of the Easter eggs onboard the Waverider itself, this one -- if indeed it's intentional, although it seems likely -- is a blink-and-you'll-miss-it kind of thing. In the recently-released trailer for season 3, eagle-eyed fans might notice a group of acrobats training in the background of a shot or two whose costumes closely resemble Tim Drake's Robin costume.

A red unitard and yellow belt over green leggings has actually been the costume for all the Robins since the New 52 reboot seemingly removed the bare-legged, pixie-booted Robin costume from continuity -- and that's handy trivia to know since it isn't Tim Robin but Dick Grayson who (along with his family) performed at a circus throughout most of his young life.

So...are the Flying Graysons part of P.T. Barnum's circus?! As far as we know, the family of acrobats and trapeze artists never joined the Greatest Show on Earth -- but that's in the comics. Also, in a timeline not damaged potentially beyond repair by the events of the DC's Legends of Tomorrow season finale. In the world of Legends, anything seems possible.

When it comes to some of DC's biggest icons, Legends has typically been allowed to reference them, but not feature them right up front. Remember that season one episode in which Rip Hunter referenced "Men of Steel" and "Dark Knights" or something along those lines? Yeah, like that. It seems they may have done something similar here; B'Wana Beast gets up close and personal with the camera, while the Graysons (?) are hanging in the background, hoping to reward some attentive viewer like Starman's cosmic rod or the Jonah Hex wanted poster on board the Waverider.

Fans will get to see whether or not those acrobats ever get a name when DC's Legends of Tomorrrow returns this fall.

After the defeat of Eobard Thawne and his equally nefarious Legion of Doom, the Legends face a new threat created by their actions at the end of last season. In revisiting a moment in time that they had already participated in, they have essentially fractured the timeline and created anachronisms – a scattering of people, animals, and objects all across time! Our team must find a way to return all the anachronisms to their original timelines before the time stream falls apart. But before our Legends can jump back into action, Rip Hunter (Arthur Darvill) and his newly established Time Bureau call their methods into question. With the Time Bureau effectively the new sheriffs in town, the Legends disband – until Mick Rory (Dominic Purcell) discovers one of them in the middle of his well-deserved vacation in Aruba. Seeing this as an opportunity to continue their time travelling heroics, Sara (Caity Lotz) wastes no time in getting the Legends back together.

We reunite with billionaire inventor Ray Palmer (Brandon Routh), the unconventional historian-turned-superhero Nick Heywood (Nick Zano), and Professor Martin Stein (Victor Garber) and Jefferson "Jax" Jackson (Franz Drameh), who together form the meta-human Firestorm. Once reunited, the Legends will challenge the Time Bureau's authority over the timeline and insist that however messy their methods may be, some problems are beyond the Bureau's capabilities. Some problems can only be fixed by Legends.
