E21 synopsis is now available. It states the following:

“Barry (Grant Gustin) takes drastic measures to stop Savitar. Meanwhile, H.R. (Tom Cavanagh) continues to push Tracy Brand (guest star Anne Dudek) to design the trap for Savitar and Killer Frost (Danielle Panabaker) returns with an interesting proposal.”

The proposal by Frost may help to distinguish Killer Frost from Caitlin Snow in a better way. It’s because it will tell us that if there is any Snow left there inside Frost. It will help the team as they will get to know if she needs to be captured or helped. It’s because you can’t let anyone out there to destroy everything. So, we may see the team taking some difficult decisions.

Only three more episodes are left in this season. So, whatever has to be done, needs to be done real quick. If they fail, Barry’s ladylove will end dead and that won’t be a good ending.

The Flash season 3 episode 21 will air on May 9, 2017, at 8 pm ET on the CW.
