Whilst Cisco Ramons lightheartedness and geekdom is one of the highlights of The Flash, he kind of oversteps the mark a little when he mocks Harry Wells for giving Zoom the name of, err, Zoom. From there, we get Harry doing his best creepy voice as he explains the shocking origin of the name. We have it explained to us that Zoom set up a fake hostage situation in order to attract 14 cops to the scene. Hed go on to brutally murder 13 of them, with the sole survivor saying that all he saw were his colleagues being slain by a monster who was zooming around. Said sole survivor was allowed to live in order to tell the tale to the world and establish Zoom as a truly nasty piece of work, and then the evil speedster paid the survivor a visit later that day and killed him, too. It was certainly a jaw-dropping moment to see Harry give a little bit more insight into the big bad of Earth-2.
