The introduction of a new Harrison Wells could easily set the tone for the entire season..
Each Wells serves a particular purpose, so we’re dying to know how the character evolves as Barry finds himself in a battle against The Thinker, this year’s new big bad.
Season 2 saw the introduction of the far more reliable and sympathetic Harry to help fight Zoom, and his rough edges smoothed out as the season went on.
Season 1 gave us the dastardly evil Eobard Thawne-in-disguise incarnation of the character, and he arguably remains the series’ best villain to this day.
