You enter a room where you saw RetroSpector reading a book while performing a ritual on Ace, his boyfriend with candles burning with blue flames. Ace seems to be enjoying being Retro's "Sacrifice" as he lay down in a submissive state

"So it goes here and there..." RetroSpecter chanters flips the book as he carefully follows the procedure of the Ritual*

"Hmmm...." Ace hums softly as he looks like he's ready to be "sacrificed".
