The superhero TV shows I've seen aren't much better. When "Arrow" started it was just Oliver Queen. Then it was Oliver and his bodyguard Diggle. Then it was Oliver, Diggle, and computer nerd Felicity. And now it's Oliver, Diggle, Felicity, Oliver's sister, his ex-girlfriend Laurel, her police captain father, Ra's al Guhl Malcom Merlin, and probably a few other people. "The Flash" is the same way. The first episode of "Supergirl" I think a half-dozen people knew her "secret" identity and then they've added a few more since then.
The thing is, the whole "someone learning the hero's true identity" is not only trite and cliche, but it loses impact each time you do it. Until like the Spider-Man movies it's just tedious and unbelievable that the whole freaking city doesn't know who he is.
|Secret identity that's secret! Whoa!|
I didn't go to that well too often in the Girl Power books either. In the first book the Bat
Anyway, I guess the point is the whole "someone learning the hero's true identity" thing can really be overdone, as can any trope. So tread carefully.
