The Flash Season 2: 11 Big Questions We're Asking After The Mid-Season Premiere

2. How And Why Is Eobard Back?

Yes, welcome back Eobard Thawne. The actual Eobard, played by the returning Matt Letscher, although quite where he's from, where he is, and how he got there are all up in the air. He himself seems very confused as to where he is, so there's not really much chance of us viewers knowing. He can't be from Earth One's future, because Eddie killing himself wiped out the possibility of Eobard Thawne existing...or it should have, anyway. So that means he's either from Earth Two, or more likely Earth Two's future. But even that doesn't clear things up, as he could be arriving from Earth Two's future into Earth Two, or Earth One. What does seem clear is that he's still the Reverse-Flash, though yet again that might not be as straightforward as it seems.
