Last week, Dr. Harrison Wells came out of the time-travel closet and revealed to Cisco (before he killed him) that he was from the future and his real name is Eobard Thawne (Tom Cavanagh). Those thrilling reveals were washed away as Barry went back in time.

If you're worried that Barry's time-travel will prevent the show from revealing the truth of Dr. Wells to the STAR labs team, don't. “Barry is going to find out in the next couple of episodes,” Grant Gustin told EW. “Joe [Jesse L. Martin] and Barry refocus all of their energy on Wells.”

Barry will become more suspicious of Dr. Wells in tonight's "Rogue Time" episode. You'll have to tune in to find out what triggers that reaction, but Cavanagh reveals that he has been using his knowledge of the future to put things into place. “Harrison Wells is not as dumb as he looks,” Cavanagh told EW. “By that I mean things that perhaps seem accidental that we’ve been watching in the first 15 episodes have not been accidental. You don’t get to come back in time and travel back and forth unless you have a certain modicum of intelligence and have thought things through. What looks like discovery on the part of our dear friends, I would tease by saying it’s not so much discovery at all.”
