The second Cisco heard that Dante was dead, time stopped. His brother had been hit by a drunk driver on the road. After being rushed into an ambulance and sped to the ER, he'd been pronounced dead at the hospital. He'd been at the lab at the time, with Barry and Caitlin in the room. It felt like reality had been torn away from him, spiraling away. He'd told them what happened, begging Barry to change the timeline and save his brother. I can't do that, Cisco. It's too dangerous, Cisco. I'm sorry. He had started going to the gym, speaking at the grief circles. Nearly every day he'd asked Barry to change the timeline again. Every one of those days Barry had refused. Then, when the Other Barry from Flashpoint had arrived, telling them he'd altered the past for himself, but not for Cisco, it felt like Dante had just died all over again. It hurt. Too much. Too much to handle. And now, standing on the roof of STAR Labs, it came to a peak.
