Following the Reverse Flash's demise, Barry Allen (Grant Gustin) inherits STAR labs with one catch: he must watch a video message left to him by Harrison Wells. In this latest clip from "The Flash" season two premiere episode, Wells' attorney tracks him down after months of no contact -- with an ultimatum.

"When we open the premiere, you'll see that it's not quite where we left off," executive producer Andrew Kreisberg told The Hollywood Reporter. "The mystery of what happened that day and how they solved the issue of the singularity is part of how the episode unfolds. Like Joe (Jesse L. Martin) says to Barry in the premiere, 'You made a really bad decision and we've all paid for it. But the real question is: What are you going to do about it?' The first episode is about Barry learning to move forward again. We have a whole new mythology this season. We're putting time travel aside and dealing with multiple Earths and the multiverse."

Starring Gustin, Carlos Valdes and Jesse L. Martin, "The Flash" returns to The CW on Oct. 6 on at 8 p.m. EST.
