I really liked that scene as well. There's a funny bookend to it as well later. I thought that it played against stereotypical tropes. Poorly characterised versions of that would have had Lois get jealous or Wonder Woman trample on Lois' grief with her own. But they don't go that way and both Lois and Wonder Woman are treated very well by that scene. Their friendship when written well makes a lot of sense. Greg Rucka had a good scene with the two of them in his Adventures run. Lois is leaving for an overseas assignment and she asks Diana to look after Clark while she's gone. No surprising Rucka can write them both together without unnecessary drama.
