"[With] Eobard as Harrison last year, there was a certain intelligence and charm and mannered way to him - a thoughtfulness.

"Barry is wanting to trust him...and in a way is quicker to trust him than he was to trust Jay [Garrick]," Gustin told TV Line. "He's less of a bad guy and more of a douchebag."
