You know, I did all this work, wrote out all these different character capsules and did all these scene skeletons...

...And I never figured out what our protagonist's abilities actually are. I mean, I know she [i]has[/i] some (in a sort of Tony-Stark-meets-Hank-Henshaw kind of way), and that she's going to need to stand up to her sister's frankly almost deific powers, but...well. That took a little while. 

I still got my words out, but I kind of wound up staring at my cat for an hour or so, thinking. I kept coming back to the idea that Protagonist doesn't want to [i]destroy[/i] her sister or anything she stands for, she just wants to be enough of a threat that she can't be ignored. That means she's going to be built much more for the idea of [i]surviving[/i] her sister than anything else, and then I could work from there.

Words are still coming easily. I hope it stays that way. :3
