When it was revealed that Matthew Letscher would be returning to The CW's "The Flash" to reprise his role as Eobard Thawne, aka Reverse-Flash, speculation began percolating about how that could be possible. After all, the character met a rather decisive fate at the end of season one. In a new conversation with EW's Spoiler Room column (via ComicBook.com), showrunner Andrew Kreisberg explained just how Thawne will re-enter the scene.

Many fans expected this Reverse-Flash to come from Earth-2, but Kreisberg said that won't be the case. "Time on our show does not unfold linearly," the executive producer explained. "Sometimes you've seen events from one direction and then you start to see them from the other. This Reverse-Flash is not exactly the Reverse-Flash that we saw disintegrate at the end of the year. It's a Reverse-Flash from an earlier timeline. It's not the Earth-Two Reverse-Flash, it's the Reverse-Flash. That is, hands down, one of our best episodes."

So it Reverse-Flash will be the Thawne we know, he just won't be the same Thawne we knew at the end of season one. Apparently one of the show's best episodes, "The Reverse-Flash Returns" airs on January 26 at 8 pm EST, and you can find the synopsis below. "The Flash" returns from its winter hiatus one week prior on January 19.
