Thwarted, imprisoned, and unshaven, The Flash's Eobard Thawne paints a perfect picture of misery...or so you would think. Flashpoint certainly threw the speedster a curveball, but Barry Allen's mortal enemy will be in good spirits when season 3 begins.

After all, this is one man who knows that messing with time isn't all it's cracked up to be.

Barry Allen (Grant Gustin) blasted back to the night of his mother's murder in the season 2 finale, and, this time, his future self wasn't on hand to warn him off. The Scarlet Speedster took the opportunity to send his mortal enemy flying, save his mother, and reset his timeline. When the fall premiere picks up three months later, the Reverse Flash (Matt Letscher) will delight in the fact that the Flash is walking a dangerous path.

"It's safe to say anything that causes Barry pain, the Reverse Flash is completely behind," Letscher told Comic Book Resources. "You know, Barry messing with the timeline -- as all tried and true science fiction can tell -- is never a good thing. Anything causing problems for Barry, he's on board with.

It will take the eponymous hero a little time to realize that all is not well in his new reality, but by time the events of "Flashpoint" transpire on Oct. 4, the savior of Central City will know all is not well. Barry's face is a mask of anger and steely determination in the SDCC first look teaser, and it's all thanks to a convo with his least favorite prisoner.

"In three words, can I sum up "The Flash" season premiere..." Letscher mused. "I'm not great at this, but I would say, "Barry's in trouble." Barry's in trouble!"

Uh oh...
