After that world-changing, timeline-shifting finale to Season 2, we're all eagerly awaiting the premiere of The Flash Season 3. Tons of new villains have already been confirmed, as the radically different, post-Flashpoint world was teased in trailers. But it's difficult to keep up with all the news, rumors, and spoilers, so we've compiled a handy guide to prepare you for CW's The Flash Season 3.

The Flash Season 3 News, Rumors & Spoilers

Updated 09/29/16:

CW have released the synopsis for Season 3 of The Flash, which suggests that the Flashpoint event may end far sooner than fans originally thought.

Executive producer Andrew Kreisberg revealed to TVLine that the door has been left open for actress Shantel VanSanten to return next season in the role of Patty Spivot. Kreisberg explained that:

“We have not seen the last of Patty. We very consciously did not kill her.”

The villain for Kevin Smith's episode of The Flash Season 3 is highly likely to be Killer Frost — Caitlin Snow's evil alter ego from Earth-2.

Smith posted the first page of the script for this episode to Instagram, and although he covered the title of the episode with a pen, the beady-eyed folks over at Cinemablend spotted that the title of "Killer Frost" bled through from the second page — if you squint.

Previously appearing in several episodes of Season 2, Killer Frost is a fascinating character that added some nice variety to Caitlin's character, even if she was just a doppelgänger. Of course, Zoom already killed Killer Frost, so there's two options for her return — either this is the Earth-2 Killer Frost, returned from the dead, or the Flashpoint Caitlin Snow will go bad.

Instagram does seem to be the best way of dropping plot hints for Season 3 — recently Grant Gustin posted a new set photo, baffling his followers. He appears to be in some kind of subterranean room, with signs of damage on the walls, and the central pillar seems to be broken off.

This could happen after a fight with the mysterious hooded figure we saw in the trailer — this figure was shown in the same room with a number of followers.

Check back here for more updates as we get closer to the release of 'The Flash' Season 3!

The Flash Season 3 Air Date

The Flash's CW premiere date was October 4th 2016, at 8pm EST. The episodes will continue to air on Tuesdays at 8/7c.

The Flash Season 3 Trailers, Previews & Promos

There have been two trailers so far for The Flash Season 3, each with their own wealth of plot hints. The first trailer introduced the main villain for Season 3 — Doctor Alchemy — as well as establishing that this really is a bold new timeline.

The next trailer may have been shorter, but it contained some vital spoilers. Barry was shown working with Wally (now Kid Flash), and sharing a moment with Iris, who isn't aware of who he is. Barry also revealed the secret of Flashpoint to Cisco, despite the fact that this Cisco is a multi-billionaire and not a simple scientist.

Some promo photos have also been released, teasing significant scenes from the first episode of Season 3.

And the final trailer for The Flash Season 3 has revealed that Barry will start to forget his previous life...

At least there's another Flash to help him out!

The Flash Season 3 & The Flashpoint Comic Book

When it was confirmed that Season 3 would indeed adapt the comic arc Flashpoint, we thought we knew what to expect.

After all, there are clear villains in the Flashpoint comic, and the Citizen Cold arc in particular seemed perfect to incorporate into Season 3. To break it down for you: In the comic, Barry Allen wakes up to discover that he has no powers, and the world is much different from what he knew. His mother is still alive, Thomas Wayne (not Bruce) is Batman, the Amazons and Atlanteans are at war — and Leonard Snart is the hero of Central City, known as Citizen Cold.

When the finale of The Flash Season 2 reset the timeline, fans assumed that Season 3 would incorporate many aspects of the Flashpoint comic arc. However, now we know this isn't the case. The main villains for Season 3 are Doctor Alchemy and Savitar, as Leonard Snart is far too busy joining the Legion of Doom in Legends of Tomorrow Season 2.

So what do we know about the Flashpoint arc in The Flash Season 3? Although it will have huge consequences that ripple out throughout the season, the time we spent it this altered timeline will be brief, as Grant Gustin revealed a few weeks ago.

Cisco might play a big role in resetting the timeline — in a new interview with Collider, The Flash Season 3 cast member Carlos Valdes hinted that although Cisco will be radically different, his role as Vibe is far from over.

It remains to be seen whether we'll see Vibe in the new, altered timeline, or if Valdes was referring to after they reset time to the way it was.

The Flash Season 3 Cast & Characters

— Grant Gustin / The Flash: Previously appearing on Glee, Gustin plays Barry Allen, a perpetually late and good natured CSI whose life is changed when he is struck by lightening during a particle accelerator explosion. Gaining superspeed, Barry becomes the Flash!

— Candice Patton / Iris West: Previously appearing on The Game, Patton plays Iris, who is Barry's longterm love interest from the comic books. On The Flash TV series, Iris slowly discovers his secret identity of the Flash, while she investigates the strange goings-on in Central City as a journalist at the Central City Picture News.

— Carlos Valdes / Cisco Ramon: A nerdy and excitable scientist, Cisco helps Barry harness his abilities as the Flash, creating Barry's supersuit. Later on, it is revealed that Cisco also became a metahuman during the explosion, and is developing powers as the superhero Vibe. Valdes is also a professional singer, and we're looking forward to seeing him demonstrate his musical talent in the upcoming Supergirl / The Flash musical episode.

— Danielle Panabaker / Caitlin Snow: A medical doctor who works at S.T.A.R. Labs, Caitlin saved Barry's life after the explosion and works to save Central City from metahuman threats. Panabaker first stretched her superhero wings in the teen movie Sky High, where she played a character with plant-manipulating powers.

— Tom Cavanagh / Harrison Wells: In Season 1, Cavanagh played Eobard Thawne, who was disguised as the deceased Harrison Wells. In Season 2 Cavanagh returned as the real Harrison Wells from Earth-2, this time more of an antihero than a villain.

— Jesse L. Martin / Joe West: Surrogate father to Barry and actual father to Iris, Joe works as a police detective, teaming up with the Flash to protect Central City from metahuman threats.

— Keiynan Lonsdale / Wally West: Iris' brother joined the show in Season 2, and Wally's adrenaline-seeking ways soon caused trouble for Barry and Iris. In Season 3, Wally will fulfill his role from the comics and become Kid Flash.

— John Wesley Shipp / Henry Allen: Barry's father was incarcerated for much of Season 1 and 2, and was killed in the Season 2 finale. However, Henry will return in as a major The Flash Season 3 character, now that Barry has reset the timeline. Shipp also played the real Jay Garrick at the end of Season 2, in a nod to his time portraying the Flash in the 1992 TV show.

— Tom Felton / Julian Dorn: Joining the cast for Season 3 is Felton, portraying a mysterious new character who will be a rival to Barry.

The Flash Season 3 Villains

As in previous seasons of The Flash, the villains are all-important in Season 3. There are two that seem to be main antagonists — Doctor Alchemy and Savitar.

Doctor Alchemy is a rather obscure villain from The Flash comics, giving the writers plenty of freedom to reinvent the character. In the comics, Dr Alchemy suffers from multiple personality disorder, meaning that we may not discover his true identity until later on in Season 3.

Another obscure villain, Savitar is a speedster from the 1990s Flash comics. The villain originated in Russia and thanks to his research into the Speed Force, Savitar has the ability to give other people speedster powers.

The Flash Season 3 will also feature another speedster known as the Rival, who we saw in the trailer.

And then there's the rest — a few more The Flash Season 3 villains have been cast, but it seems more likely that they'll be one-episode-wonders
