Did You Know?


The idea of a Time Wraith appearing because of an incident involving time travel is very similar to the 2005 Doctor Who episode, Father's Day, in which Reapers appear because of a rip in time. See more »


Just before the Time Wraith attacks Caitlin, she looks at her phone because she thinks it's vibrating. Her phone is an iPhone 6. At this point in time in the Flash story line, iPhone 6s had not yet hit the market (as the release date for the episode in which these past events occur predate the release of the 6). See more »


Barry Allen: [arriving back] It's coming!
Caitlin Snow: Did you even go?
Barry Allen: The Time Wraith.
Cisco Ramon: That's a good name.

User Reviews

the best episode yet in the show!!
30 March 2016 | by YadhuDeHosureSee all my reviews

As my caption suggests this is the best flash episode indeed.. Using the concept of time travel and picking the pieces left in the past to move on was the entire episode. This episode in my opinion has the least soap with Father-son or Father- daughter or Barry-Iris dramas.I was glued to my seat throughout the episode. When we got to see Eddie again, we were thrilled. But the only part disappointing was that Barry disturbed the time line.. Now we can expect many changes like The pied Piper joining team flash. But , other than that all the things about two flashes and Eobard Thawne giving Barry tips about increasing speed force with Tachyons was splendid indeed.
