According to the synopsis, Wally has been having visions of Savitar during his training sessions with Barry Allen/The Flash (Grant Gustin) and decides to keep it a secret to him and the rest of the team. Meanwhile, a dangerous secret will have an effect on Barry Allen and Iris West's (Candice Peyton) relationship.

Could this secret have something to do with Wally's visions of Savitar's return to the show leading to Iris' eventual death in the future timeline that Barry tries to prevent?

It is previously hinted that Savitar's prophecies could have a huge effect on the West family in "The Flash" season 3 as it theorized that Wally West/Kid Flash could be the one to betray Barry and Team Flash, Iris will die at the hands of Savitar just like in the future and Joe will suffer a fate worse than death seeing as what has happened to his children, ComicBook reported.

The second haft of season 3 is focused on Barry and Team Flash trying to change certain events leading to Iris's eventual death at the hands of Savitar and The Flash has been preparing Kid Flash to save Iris from the speedster god if he fails to do so.

In other news, it seems that a new metahuman character will be appearing in "The Flash" season 3 as The HollywoodNorth.buzz tweeted behind-the-scenes photos of Team Flash consisting of The Flash, Kid Flash and Vibe (Carlos Valdes) taking on a white haired individual.

It speculated that the character could be the show's version of Max Mercury, another speedster in The Flash mythos. Max was the first human to ever tap into the Speed Force, a friend of Jay Garrick, and is a mentor to both Wally West and Bart Allen in the comics. He also has white hair, although he usually wears a blue and white costume, rather than the black that this character is seen in, Screenrant reported.

There is also the matter of the Accelerated Man appearing in "The Flash" season 3 and it is rumored it could be Eddie Thawne (Rick Cosnett) from another alternate Earth.

"The Flash" returns on Tuesday 8pm on the CW Network.
