User blog comment:Wales8450/Is Eobard Thawne (Matt Letscher) fully alive again???/@comment-28258486-20161005193041/@comment-3221148-20161006132605

Let's wait for Episode II before we sure if this is Wells-1 or Harry. My money's on time remnant Wellsobard still appearing and killing Wells-1, just to make Barry's story work.

The prime paradox now is that we have two incompatible speedsters: Eobard with the knowledge and memories of 2020-Accelerator timeline, and Barry with knowledge and memories of 2013-Accelerator timeline. To resolve the paradox, a separate Wellsobard is needed.
