The Flash Featurette Introduces Us To A Key Character In The Savitar Mystery

Tonight’s episode of The Flash will finally reveal who’s beneath Savitar’s mask, and a new featurette for the upcoming outing that was released this morning drops some big hints about what’s next for Team Flash as they look to stop the self-proclaimed Speed God before he can murder Iris West in cold blood.

After paying a visit to the future in last week’s instalment of The CW series, the Fastest Man Alive is now on the hunt for a physicist named Tracy Brand (Anne Dudek). Four years from now, she creates the device which traps Savitar in the Speed Force, so Barry is hoping that this earlier version will be capable of doing the same thing.

For more on what to expect from the next episode of The Flash, here’s the official synopsis for “I Know Who You Are.”

Barry (Grant Gustin) and the team meet Tracy Brand (guest star Anne Dudek), a scientist, who may be the key to stopping Savitar. Unfortunately, Killer Frost (Danielle Panabaker) is also after Tracy so Team Flash must battle their old friend, which proves to be particularly difficult for Cisco (Carlos Valdes). Joe (Jesse L. Martin) and Cecile’s (guest star Danielle Nicolet) relationship takes a big turn.

Since Killer Frost aligned herself with Savitar, it’s become clear that he’s someone the team knows. The prevailing theory is that it’s Ronnie Raymond beneath the mask (Caitlin Snow’s husband who was seemingly killed in the season 2 premiere), but we’re not going to get any definite answers until this episode of The Flash airs later tonight. The odds are stacked against the team, though – that much is for certain – and stopping Savitar won’t be easy, regardless of how helpful Brand winds up being.
