Something has reduced The Flash cast to tears.

'The Flash' Season 2: Will Trajectory Land Barry In Prison? Meet Central City's Next Speedster

Episode 17 is underway, and Grant Gustin's (Barry) reaction to the script is making us very nervous. The untitled hour elicited tears from several of the series' leads, including the speedster himself.

As much as we'd like to believe those we're tears of laughter, Danielle Panabaker's (Caitlin) tweet threw that idea right out the window.

Is there a death on the horizon? A heart-breaking reveal? Will we finally find out who’s hiding behind Zoom’s mask? With Iris’ (Candice Patton) mother on her deathbed and The Flash’s decision to tip their hat to Hunter Zolomon in “The Reverse Flash Returns,” any of these situations are a possibility.

Of course, it could be none of the above. Barry, Cisco (Carlos Valdes), and Harry (Tom Cavanagh) will head to Earth-2 in episode 13, and it’s a safe bet that they’re the storyline will receive a bit of a shakeup when the Scarlet Speedster heads through the breaches. If season 2 is anything like season 1, there are plenty of twists still to come.
