‘The Flash’ Season 3 Spoilers: Barry To Meet Black Flash? Grant Gustin, Showrunner Weigh In On Plot Twists

Avid viewers of "The Flash" Season 3 witnessed beloved characters of the CW show succumb to Savitar's plans that led to Wally's (Keiynan Lonsdale) imprisonment inside the Speed Force. Latest spoiler news teased of the scarlet speedster's attempt to rescue the Kid Flash, as well as a potential encounter between Barry (Grant Gustin) and the Black Flash.

"The Flash" Season 3 episode 15 featured Savitar's escape from the Speed Force at the cost of Wally's freedom. Titled "The Wrath of Savitar," two of the said villain's prophesies came true with the Kid Flash identified as the person who will suffer a fate worse than death and Caitlin (Danielle Panabaker) as the character who betrayed Team Flash given the piece of the Philosopher's Stone that she kept hidden from her friends.

Aired on March 7, the said "The Flash" Season 3 also included Barry and Iris' (Candice Patton) engagement which was put on hold after the bride-to-be discovered that her fiance only proposed to alter future events. In Barry's accidental trip to the future where he witnessed how Savitar killed Iris, he noticed that his girlfriend was not wearing an engagement ring. Thinking that proposing in the present time will help to change her fate, Barry asked Iris if she could marry him.

In an interview with Entertainment Weekly, Grant Gustin and showrunner Andrew Kreisberg shared their thoughts about Barry's motives. The CW show's executive producer described Barry's decision as an act of desperation while the actor labeled it an act of fear.

Kreisberg shared that although Barry and Iris truly love each other and would want to spend their lives together, the main reason behind the Flash's marriage proposal was wrong. The showrunner even teased that the stress of having to change Iris' impending death will "damage" the couple's relationship.

Meanwhile, the upcoming "The Flash" Season 3 episode 16 will have Barry meeting some familiar faces as he enters the Speed Force to save Wally. A teaser clip posted on Spoilers Guide unveiled some of the deceased characters that the scarlet speedster will encounter such as Leonard Snart (Wentworth Miller), Iris' former boyfriend Eddie Thawne (Rick Cosnett) and Ronnie Raymond (Robbie Amell). Barry may even meet the Black Flash during his deadly sojourn inside the Speed Force.

"The Flash" Season 3 episode 16 will be released on March 14 on the CW. Watch a teaser clip below:
