The Flash Season 3 started with a bang, and now we're deep into the consequences of this post-Flashpoint timeline. What is Doctor Alchemy planning, and will Caitlyn become the villain Killer Frost? 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 11/17/16:

The new villain for The Flash Season 3 has been revealed — named Savitar, this speedster appeared at the end of S03E06, claiming to be the "god of speed."

As there's already a speedster god in the DC Comics, we're left wondering whether Savitar is indeed a godlike being, making him the most formidable foe Barry has ever faced. Of course, he might just be a human with some serious delusions of grandeur.

In a new video, the costume for Killer Frost has been revealed.

This costume looks a lot like a superhero suit, but it also seems to be kept on the same clothing rack as the villain costumes.

The official synopsis for Kevin Smith's upcoming episode has been revealed. As rumored, this episode will indeed feature the appearance of Killer Frost, but not the Earth-2 version of the villain. After Barry's attempt to restore the timeline, we discovered that Caitlin now possesses frost powers, like her Earth-2 doppelgänger.

Last episode saw Caitlin seek her mother's help, and it seemed as though she might have her abilities under control. But it looks like that's all going to change in Episode 7, as the new synopsis reveals:

KEVIN SMITH DIRECTS; KILLER FROST EMERGES — Caitlin (Danielle Panabaker) uses her powers to save Barry (Grant Gustin) but as her mother predicted, the effort unleashes her inner Killer Frost. Killer Frost goes on a rampage looking for Dr. Alchemy, kidnapping Julian (Tom Felton) and battling both The Flash and Vibe (Carlos Valdes). Meanwhile, Joe (Jesse L. Martin) and H.R. (Tom Cavanagh) have a heart to heart talk.

It'll be interesting to see how the writers, and director Kevin Smith, handle Caitlin's abrupt turn to evil. We know she has a short temper, and some serious issues with control, as she turned on her mother's lab assistant last episode. However, she has proven time and again that she's loyal to Barry and Team Flash, and ultimately she wants to help people.

Executive producer Greg Berlanti revealed to Entertainment Weekly that we will never return to the original timeline.

After Barry reset the timeline — twice — Season 3 is dealing with the consequences of time travel, and the post-Flashpoint timeline has many key differences to the timeline from Season 1. Although some fans want to see the old timeline restored, Berlanti has shot down these hopes:

“I’m not sure that we can [return to the original timeline], given what we’ve established. If we’re not challenging ourselves and creating new territory and new obstacles for the characters, I think it’s less rewarding to watch and probably less rewarding to play. We like to grow ourselves and grow our characters.”

Of course, it's worth noting that the timeline explored in Season 1 wasn't even the original timeline — the Reverse Flash changed this when he first went back in time to kill Barry's mother. Thawne then had to disguise himself as Harrison Wells in order to correct the new timeline's course so that the particle accelerator would explode, and Barry would become the Flash.

Berlanti did not confirm whether we'd see further alterations to the timeline in Season 3, or later on in the show.

Some alternatives to Jesse Quick's new costume have been released. They're pretty streamlined but her final outfit lines up nicely with the Earth-2 retro aesthetic, while the alternate costume is far more modern.

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.”

In the meantime, Mirror Master's appearance on The Flash Season 3 Episode 4 has raised some questions about Captain Cold's role in Legends of Tomorrow: In the post-Flashpoint timeline, did he even join the Legends in the first place?

It looks like Caitlin will finally become the villainous Killer Frost next episode, as this promo reveals.

But will she stay bad?

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.

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. The alternate timeline known as Flashpoint did feature differences like Cisco Ramon being the richest man on Earth, but it had few similarities to the comic book.

The consequences of Flashpoint will ripple out throughout Season 3, as Doctor Alchemy recruits people with the promise of restoring their Flashpoint powers.

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.

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
