I don't know how to get the last two H scenes of the Gallery, the one of zellen and one in the bed with MalO
For Zellen scene I did:
-Expand territory
-Tell Won about Mal
-Show Mal
-Manipulate reality
-Bathroom scene
-Cage Mal
-Release Mal
-Find Zellen
then you should have two options of telling or not Zellen, if you tell her it'll be Zellen scene if you don't it'll be Mal scene
Bdw dere is way for romb (2th ending)do same ting but do not release MalO and you get it
