"Crossfire, Part 2 of 5: Hide and Seek"
*With the Rogues on one side and the Thinker on the other, Flash realizes the only hope for Central and Keystone Cities is if he lives, so he races into Keystone to retrieve the cure for Murmur's virus. The Thinker tells him that everyone in the city is plugged in to his system. He doesn't know that Chyre and a healed Morillo have been able to overpower Plunder and convince that Morillo is his double, or that Captain Cold can stay safe due to his cold field and Kenyon is also on the loose. As Morillo and Chyre head into Central City to free Cyborg, encountering Captain Cold along the way, the Rogues head in the opposite direction and discover that Thinker has taken over Flash's brain in Keystone. *Source: dcuguide.com
