I Know Who Your Are



Critic Consensus: Just like Savitar, "I Know Who You Are" is dark, mysterious, and full of shocking twists -- even if the episode's big reveal feels a tad dragged-out.

Episode Info

Barry and the team meet Tracy Brand, a scientist who may be the key to stopping Savitar. Unfortunately, Killer Frost is also after Tracy, so Team Flash must battle their old friend, which proves to be particularly difficult for Cisco. Meanwhile, Joe and Cecile's relationship takes a big turn.

Critic Reviews for I Know Who Your Are

An amazing blend of CGI and camerawork that produced sheer greatness.

This week's Flash was a very mixed affair... There was too much filler leading up to the big Savitar reveal, but at least that reveal promises to re-energize the series.

My head's starting to hurt.

After a rough introduction this season, HR has found his place on Team Flash (and on The Flash) and has a purpose. His interactions with Tracy were a highlight of the hour.

It's powerful, poignant, and dark, but unlike previous episodes, it earns that darkness and doesn't wallow in it.

It plays out as unjustified self-congratulation for dragging out the big mystery for much longer than necessary.

Danielle Panabaker has never been more thrilling than when she plays Killer Frost.

'I Know Who You Are' is an episode that's mostly concerned with the big reveal coming in its finale minute, and because of this, much of the development for any other subplot feels like an after thought.

This week's massive Savitar twist was executed perfectly.

I Know Who You Are finally delivered on the season's biggest mystery - Savitar's identity. Did it deliver? Mostly.
