The Flash: Team Flash Suffers a Major Loss in "All's Wells That Ends Wells" The Flash saw Team Flash facing one of the most complicated challenges they have to date. Thanks to the death of the Speed Force in Season 6, Barry Allen/The Flash (Grant Gustin) has been steadily running out of speed and the timing couldn't be worse. Eva McCulloch (Efrat Dor) is on the loose in the real world while Iris West-Allen (Candice Patton) remains trapped in the Mirrorverse. With time running out, both for Barry's speed and Iris' well-being, Team Flash had to come up with a plan to restore Barry's speed and defeat Eva -- and it's something that saw a major loss for the team.
