Rose: Go dark.

Notes:

This image was created by Andrew Hussie for the webcomic Homestuck on March 15, 2011, and features the original interpretation of Rose Lalonde becoming grimdark, with grey skin and glowing eyes, plus black substances coming out of her body to represent the state of grimdarkness.

Rose also speaks in eldritch language. Even I don't understand that gobbeldy-goop.
