I agree with Patrick that Robin may very well be Clark's cousin. Her Kryptonian name, Kara, is just too suggestive. I wonder if Robin herself believes (or knows) that she is Clark's cousin.
Personally, I can't get over her other name, Robin, either. The first Robin I ever heard of, when I was a kid, was Robin Hood. The second Robin I heard of was Batman's sidekick. So when I first learned, not until I was in my twenties, that Robin was primarily a girl's name in the United States, I almost couldn't believe it!
Anyway, Robin has got the same name as Batman's sidekick. Does that suggest that maybe this Robin could be Superman's sidekick? Or that Clark would like to see her in that role?
