The Flash Season 2 SPOILERS: Twitter Reacts Katie Cassidy Black Siren/Henry Allen Twist!

The CW Network continues with Season 2 of The Flash. With the identity behind the super-villain Zoom (voiced by Tony Todd) revealed, Twitter had lots to say about the twist between Earth-2's Black Siren (Candice Patton) and Henry Allen (John Wesley Shipp).

In our previous recap, though Wally West (Keiynan Lonsdale) and Jesse (Violett Beane) survived the blast, Iris witnessed the arrival of zombie Girder. While Girder was on a destructive path, Barry found himself stuck in the Speed Force. After dealing with the tragic death of his mother, Barry was ready to return home. After hearing Iris' voice, The Flash returned better than ever, rescuing her from zombie Girder.

In our recent recap, Zoom unleashed his army of evil metahumans upon Central City. Even with the return of Caitlin Snow (Danielle Panabaker), the Flash couldn't shake off the shock of seeing his dead friend, Laurel Lance, as Black Siren. With his team by his side, the Flash sent a pulse that struck down every Earth-2 metahuman. Barry couldn't save his own father as Zoom murdered Henry Allen right in front of him.

In an interview with Entertainment Weekly, Carlos Valdes describes the significance of Black Siren's appearance, "There's a little bit of a morbid shock, because the characters have an awareness to the fact that Laurel Lance is dead. That death had some effect on these characters in this world. So to see Black Siren, more than anything, is a shock to the senses. To know that someone relatively close to you is dead and to see a version of them still alive would be harrowing and jarring for anyone. There's a bit of a disturbance there in terms of seeing her like that again."

Check out what Twitter had to say:

@FlashTVNews tweets, "Forever grateful that #TheFlash producers had cast @JohnWesleyShipp as Henry. My childhood hero and Flash."

@CANDICEPATTONN adds, "When you're happy WESTALLEN is canon but not fully bc Henry is dead #TheFlash"

@AlleciaHardeman writes, "My Twitter page is starting to look more like a grieving page for Henry Allen Damn #TheFlash why did you do this to me?"

@MsApril04 states, "Cisco saw the future.. Wally found out the truth.. Then Henry died. Ok, too much for an episode. #TheFlash"

@serena1694 praises, "@JohnWesleyShipp I'm so sad that Henry is gone, you portrayed him wonderfully and I'll miss you but you'll always be part of #TheFlash"

@TheVideoGamHer loved the reunion between Shipp and Amanda Pays, "On last night's #TheFlash when Henry and Dr. McGee were like they never met each other before I smiled so big lol. Like yeah...ok...."

The Flash continues on the CW for 1 more Tuesday at 8pm.
