What brings Superman to National City?
The two of them actually show up to the same crisis. It wasn’t a turf war, they just both heard about the same tragedy on the news and both flew into action. But they haven’t really gotten a chance to spend time together, especially since she’s come out as Supergirl, and they both want that. Both of them have a bit of sadness about them, they both have that sense of feeling alone, they both have that sense of feeling different, and both of them remark that that loneliness, that alienation, that isolation goes away when they are together. Part of what these episodes explore is that they don’t get that because of the machinations of the plot and of the actions of Project Cadmus, the villains; they both have homes to defend and they have to defend their own turf.
