Another great meta-human villain in this episode. A man who's molecular makeup allows him to flow thru solid objects. Reese who is Hawk's son and Huntress are working together to keep Hawk safe as he is willing to turn states evidence now that his organization and Frankie Spitz has turned on him.
The problem is that Hawk is the man who got Black Canary killed and Dinah wants revenge. It turns out that she is quite a dangerous meta-human when angry and must learn to control her temper. Huntress stops her from killing him and they have an altercation.
In the end the Birds band together to defeat the wall walker by using a combination of Dinah's, Huntress, and Oracle's powers. Reese takes Hawk to jail after he decides now that there is no danger he wants to just retire and not turn states evidence. Huntress and Dinah are bonding even more. At the end of the episode there is a cute exchange between them with Dinah saying she looks better in the com than Huntress at least everybody says so "Everyone but your boyfriend!" Huntress reply's, "He's not my boyfriend!" It's a running joke now.
An enjoyable episode that flies by. One of the better overall episodes. In a way this episode is a turning point with all of the teams powers starting to come to the fore. Thanks for reading...
