On The Flash Season 1 Episode 6, Barry and Iris find themselves in a spot of trouble thanks to an old childhood nemesis. 

Have you ever wondered what might happen if the kid who bullied you in school resurfaced as an adult, bigger and meaner than ever before? I don't think Barry did, either, but he and Iris sure go the opportunity to find out.

It turns out speed isn't anything in comparison to the strength of steel, unless you know how to use it. If you run 5.3 miles and get yourself up to the speed of sound, well, you can either live to tell about it or kill yourself. Guess which Barry pulled off to save Iris!

In other big news, the Reverse Flash paid Joe West a visit when he learned about the investigation into the death of Nora and his hope to exonerate Henry Allen. That means the killer is close by, even today, and desirous of remaining hidden.

Who is The Reverse Flash? How close was Joe getting to the truth when he started digging? Learn the answer to at least one of these questions when you watch The Flash online. Click below right now!
