While fans expected Barry to be changed by his time in the Speed Force, this promo seems to confirm that he will not be the same lighthearted hero that he was when he left.
A new promo for season 4 of The Flash reveals Barry Allen’s.
Season 3 ended with Iris (Candice Patton) being saved from her fate at the hands of Savitar, but with the shocking loss of Barry himself.
One more shot sees Barry with the Speed Force lightning flickering in his eyes, looking much angrier than before, before the promo ends with Cisco saying “The Flash is back!”
