OMG OMG I JUST NOTICED SOMETHING
If you take the letters S-C-A-R-E-D-G-I-R-L and rearrange the letters and add a l, you get sacred grill.
Coincidence? I think not. Scaredgirl is obviously part of the ancient amazon warriors and she was reanimated
by an evil necromancer to act as the sacred grill on which he cooks up new mutants! God save us!
