The second step of the process to call Bellatrix back from the dead and insert her into Hermione's body was just as disturbing. Consisting of a number of different parts, she couldn't believe how complicated it all was. It was no wonder that the ritual had rarely been completed. There were numerous ways in which it could go terribly wrong. At least the high likelihood that she would die in the process gave Hermione some comfort. Even a painful death was preferable to sharing a body with Bellatrix.
