Fortunately, Dick Grayson paralyzes Emmick with his own sedatives. Dick escorts Dr. Reid to Gordon where she reveals her true identity and her purpose for joining the Cadmus crew. All she wanted was to research mental illness so she could atone for the shame her grandfather brought into her family.
