All throughout this episode and the previous two before this one, I have one big question.. When Mercy graves, her brother and Agent Liberty gasses the world with with kryptonite. we see them hurry to rescue Supergirl and get her into this armor.. My question though is what about Superman?? He never even got a small mention on how those in Metropolis were dealing with this issue.. Seems like some poor writing of this episode and the 2 previous to not even mention him at all.. Any other time name-drops are a big part of the Arrowverse series, but I guess we're just left to ponder what happened..
