We open on Daxam on The Day that Krypton Died. Fireballs are raining down on the planet and Mon-El and the Prince are running. They find a Kryptonian Ship that some dead emissaries left behind. Mon-El insists that the Prince escape in it but the Prince admits he cannot fly it. Mon-El gets in to pre-program the destination and then the Prince shut him in because he's wounded and wants to go down with his planet.
DEO. Supergirl is still being choked by Kryptonian Coma Guy [KCG]. He flips her through some glass and runs out from his medical area. The DEO agents are both incompetent and puny, so they easily tossed aside by the super strong KCG, who seems to have all the same powers as the Supers. Alex shows up and I promise you she cannot successfully wield a gun or take down a bad guy unless we are at least 30 minutes into an episode. So, instead of taking the guy down, she just yells, "FREEZE!" KCG jumps out the window, lands unharmed, and super runs his way all the way into the title card.
