Since I don't really know which one you're missing, tell me if this isn't the ending you want XD
-SPOILERS-
The 3 endings are good, bad, and extremely bad in my opinion XD considering the last one was the most uncommon, I think you might need to choose 'looks so similar but isn't him' and 'grotesque', after that I guess you can already know what's the last ending. Hope this helps you, although the ending isn't too enjoyable XD
