Thought from Infinite Crisis #2, pages 2 and 3.
1. I know how you feel, Animal Man; Troia makes me want to throw up, too.
2. There is no "problem at the center of the universe". There is no center of the universe. It's bad enough that Troia is saying it; but hey, she's a photographer not a physicist. But the goldarned Guardians of the Universe have been saying it, too. It's okay if Troia is stupider than I am; it's not okay if the Guardians are.
3. So, "Supergirl", there's no word for 'escape' in Kryptonese? Perhaps that's why no one "escaped" the explosion, huh? That's the kind of idiotic, poorly thought out flourish I'd expect from Marv Wolfman, not Geoff Johns; Marv, give Geoff the pen back! What Supergirl has claimed is pretty much linguistically impossible. "Escape" isn't an obscure concept; any culture whose members face any danger has the concept, and so, will have some word to denominate it. If nothing else, they have a word for "exit" or "get out" or "evade" or "avoid".
So either the writers are being really stupid here or Supergirl is. My money's on Supergirl. I'm kind of hoping the preservation of the universe (or multiverse or whatever) winds up depending on Power Girl dismembering and consuming all of Supergirl so as to subsume her place in reality. No "escape" for Supergirl!
