With Barry under his control, Rosso attacks Central City and converts most of its citizens into his "Blood Brothers and Sisters." Cisco and Iris disagree over how to save Barry and stop Rosso, but both of their plans fail. However, Rosso chooses not to convert them in favor of enacting the final phase of his plan: taking S.T.A.R. Labs' particle accelerator to spread his blood across all of Central City. As he makes his way inside, Cisco and Iris realize that, during their last encounter, Barry u
