Wentworth Miller has been signed as one of the villains who can appear in any of the DC CW shows. So Capt. Cold, Damien Dahrk, Reverse Flash and Merlyn can show up anywhere.

I am holding out hope that Ray absorbed the power of the suit when it exploded. It was stated a number of time that the suit was keyed to him personally. Maybe we will see The Atom reappear at some point.

Marty! What a laugh!

He seemed to have heightened reaction time… I was guessing Slade's son Grant Wilson, The Ravager… I guess we'll never know.

Don't forget, Tobias said that he would tell Prometheus and Prometheus would be the only one to know… Well, Prometheus kept the bargain and now he is the only one who knows…

I felt it was an entertaining episode. The story was more about introducing HR, fleshing out Julian's character and expanding Catlyn's story-line. A top of the line menace would have been too much for the episode. I would rather see them use a one off character as the antagonist than to use a good villain as a one…
