When listing off DeVoe's "charitable qualities", Harry said that he volunteers at an orphanage. Orphanages in America had been completely replaced by the foster care system in the United States by the early 1970s. See more »


Barry Allen: Who are you really?
Clifford DeVoe: Who's asking? Barry Allen? Or The Flash?
Barry Allen: How did you...
Clifford DeVoe: Oh, please. Your secret is one of the more underwhelming revelations I have uncovered. I was born on the same evening as you were. January 7, the night S.T.A.R. Labs' particle accelerator bathed Central City in gene-altering dark matter. We were both struck by lightning.
Barry Allen: I knew you were affected. How did our test not show your meta-DNA?

Finally someone had rolled the dice!
25 November 2017 | by asb_deutschSee all my reviews

S04E07 now makes you really care about all the characters, even The Thinker, who seemed annoying in the "Girls Night Out" episode!

I like it when Candice Patton says "And people are always going to be coming after us". Also, when The Thinker says "What is knowledge without love?" Even the writers gave some space for Marlize DeVoe, without showing her a damsel in distress!

My ratings (based on what I marked on IMDb): Season 1: 200/23 = 8.69 Season 2: 193/23= 8.23; Season 3: 188/23= 8.17; and Season 4: 46/7= 6.57 (This episode will be 7.5).

I haven't see any episode of Arrow but I hope I understand "Crisis on Earth-X". See you flash fans next week!
