Natsuki's worst nightmare after getting caught by the Revenant.

Natsuki as Blitzo

Yuri as Stolas (Yuri is a reaper and has the same stab wounds)

Ziggy as Moxxie 

Natsuki's dad as Striker

Sayori as Fizzi (Sayori looks just like the Scarlet King despite the noose around her neck)

Monika as Verosika (Glitched out due to being deleted)

Great Death and Small Death as the two Blitzo figures fanning Stolas and All Death is behind Yuri's throne

After the whole "You're gonna die alone" bit, I believe there would be something extra but I know Rosie would appear after that but I don't know when.
