Like the others so far, a decent episode.
I was really disappointed that Plastique died. And also disappointed that she ignored Sisko.
I was really confused with the Iris storyline. Wally realizes that Iris is looking into the Flash because of their friendship and this makes him happy, but then he tries to stop her again and says they shouldn't talk anymore. How does that help? And why is it worth estranging the person he cares about most? Just seems like conflict for the sake of conflict. In reality he'd just tell her the truth everyone else in his circle knows. How does it protect her to keep her in the dark. It actually hurts her because villains might realize they are close, but she doesn't know she might be targeted.
I agree that the Barry/Iris conflict is rather needless. Barry is shoehorned into the promise he made to not tell her out of the old cliche that it will put her in danger.
Seems pointless to me, especially if Wells really IS Professor Zoom then he knows ALL about her and her fate, etc.
