She also knew about the setup of Rachel, which Mark, Monica, Tracy and the others organised. Rachel snaps because of it and causes the Black Party.
Deborah felt terror, when Rachel unleashed her telekinetic abilities and ran mindlessly around the house because of it. She was killed by flying CDs, who went into her body. They were launched by Rachel on her through her unleashed telekinetic powers.
