Crisis on Infinite Earths: Part Three
Outcast enrolls Black Lightning to help stop the Anti-Monitor after the Flash of Earth-90 offers what he gained from his fight in 'Elseworlds'. With the assistance of Black Lightning, Barry, Cisco and Killer Frost think of an arrangement that could spare them all. In the interim, Iris shows some kindness to-heart with Ryan Choi while Oliver and Diggle come back to an old recognizable favorite spot.
