Upon first coming out of her coma, The Bride believes her unborn child was killed in the attack and promises to avenge her death. The audience does not learn that she is alive until the last line of Vol. 1, and The Bride does not find out until the final act of Vol. 2. B.B. was named and raised by Bill, who was always open with his daughter about the terrible crime he had committed against The Bride.
