BARRY DECIDES HE NEEDS TO PROTECT THE CITY ON HIS OWN — Picking up months after the Singularity attacked Central City, Barry (Grant Gustin) is still struggling to forgive himself for Eddie’s death. Concerned about putting his friends in danger, Barry has pushed everyone away and has chosen to protect the city on his own. When a meta-human named Atom Smasher (guest star Adam Copeland) attacks the city, Iris (Candice Patton) tells Barry that he needs to let his friends help him protect the citizens of Central City. Meanwhile, Cisco (Carlos Valdes) helps Joe (Jesse L. Martin) with his Meta Task Force. Ralph Hemecker directed the episode with story by Greg Berlanti & Andrew Kreisberg and teleplay by Andrew Kreisberg & Gabrielle Stanton (#201).
