Katya walked on broken glass for the first time in December 2007 after taking a "correspondence course" (read: picking someone's brain and reverse engineering the act). She performed a flesh pull on broken glass with Steve Walsh and Nizzle at the Labrynith on January 19th, 2008. Sometimes the glass is set ablaze.
Because people have said that she's too pretty to put her face in broken glass, she continues to put her face in broken glass without ever being cut. Put best by a heckler: "'No'" means 'Yes', and 'Yes' means 'Yes'". That which is frightening or unimaginable to the rest of the population inspires Katya.
