I mean that was the issue and they did dance around it several times. But they never brought it up that "directly". And that is what was most annoying about it.

Just sit down and have her explain how she had been there. How she knew from experience. Were left to assume that or read it in as subtext largely. Which makes what could have been part of a great character arc come off as a bit preachy and unearned without that necessary context. Unless you assume that was why. And if you have to make assumptions. Then something is wrong with the storytelling.

That, and the swordsmith's daughter deserved a bit more agency and a small arc as well. Saving Supergirl from the green sun was good. But giving her some minimal fighting or sword skills as well would have been so much better. Turning her from a mostly useless tagalong. To part of a proper adventuring duo. She still could have been a kid in over her head. Just not as much dead weight.
