Will Eddie Thawne Return Season 7?

Eddie is going to return to get his revenge on Barry and Iris because Iris kinda... ... moved on and Barry basically ran away with Iris into the sunset. Also, in episode 3x16, Eddie says the same line as Eobard Thawne. "Ever the hero, huh, Barry?" (and this is when Eddie is in the Speed Force).

Is Eobard Thawne coming back for Season 7?

To that end, Reverse-Flash's return in The Flash's season 7 finale brings back Eobard as Wells, which certainly feels like a season 1 callback considering that Barry got to know this version of the villain the best out of all the other iterations.

How is Thawne back in Season 7?

The final battle with Godspeed (Karan Oberoi) in The Flash season 7 finale offered a shocking twist with the reveal that Barry's secret weapon against Godspeed was Reverse-Flash. Apparently, the Speed Force (Michelle Harrison) – at Team Flash's request – used the Negative Speed Force to resurrect Thawne.
