"It's more than just a memory," he says, trying to clarify. "I know that it happened. It's too vivid and clear for it not to have." He remembers every detail. The moment he decided to trust Jay. The moment Jay killed himself in front of him. Everything that he had done as Zoom and the moment he'd taken the last parent Barry had from him.

Felicity didn't know about his father. At least as far as he knew. He'd been too wrapped up in his own grief to let anyone in their immediate circle know and he hadn't wanted to admit it out loud or through text. Even now, far away from his normal life, he didn't want to say it.

"I remembered Zoom," he says finally, glancing over at her. "Every mistake I made with him. I let him into my life, Felicity. I let him near my family and friends. I told myself I'd never let anyone hurt any of them again and I opened the door for him to walk right through."

He stops. "I didn't have time to tell you. He..." He forces himself to take a breath. "He killed my dad."
