Then this movie ends with Constantine being like, "We're fukked, mate. Just go restart everything." And Barry does exactly that.Toward the end of the movie, it dawned upon me that the reason all of this started in the first place was because Professor Zoom made a petty "You can't save everyone" remark to Flash in JL: Flashpoint and Barry got all in his feelings about it. *sighs*
The Flash is literally the cause of and solution to all of their problems.
