Unmarked spoilers are ahead, per Spoilers Off rule.
Ending B of Jennifer's Scenario, which you get if you do everything to get ending A, but then fail to get or use the dagger on Edward/Dan when he's trying to pull a Taking You with Me with Jennifer, leading into her getting dragged into the vortex alongside him, and we're then treated to a cutscene of Helen and Nolan visiting her grave.
Ending C of Helen's Scenario: which you get if you use the fireplace key to go to the church instead of encountering Gotts and getting his gun to shoot the lock, leading into you only being capable of watch as Jennifer gets killed by Scissorman, followed by getting the map and finding out about the secret passageway under the fountain. When Helen gets to the passageway, she finds Professor Barton who tells her that he found the secret to defeat Scissorman, but when Helen walks past him he then stabs her in the back, with Helen only being capable of pitifully saying "Professor?" before dying and, similar to Jennifer's B ending, we're then treated to a cutscene of Gotts visiting her grave. Compared to the one above, this ending is worse, as Jennifer B had Jennifer pulled in with Scissorman, while Helen C had Helen dying before solving the mystery and doing anything about it. As Gotts stands at her grave, you can hear scissors in the background, showing that the case still isn't closed and the murders will continue.
