Some interesting info from you, thanks, but AFAIK meeting the SWAT team stops all love routes! But you misinterpret some parts of my post. I spoke about some options how to deal with SR for all the players, not me in special, to keep it open.Abou that second spoiler, that choice has nothing to do with SR affection. Option 1 only appears if you are both on Evil route AND still on Sarah's path, willing to redeem yourself. Otherwise, you can only look how SR deals with the soldiers (either because you're already evil or don't want to raise any suspicion) and no other path is closed by that choice.. Only requiremets to get the foursome are: being still on Kat's love route while having had the library threesome with TFH back in your second visit to the village, and have NOT a perfect score with SR.
So, about the paths being closed 'just' by being nice to SR...You don't have permission to view the spoiler content. Log in or register now.
Then it's kind of disingenuous to play the game in a way that made you accumulate more evil points than good points, and when finally paired up with SR as a demon still try to get the love of your saint wife. You have already chosen your path and at this point you've already committed yourself to the evil side of the story, all your MC thoughts displayed make that clear. Being evil is what locks you out of Kat, not befriending SR
In my case, I have e.g. two Hero path playthroughs (with HPs at/near max) where I try to get friendly with Sanguis Rex. In one the Hero MC is falling for her, so cutting off the other love routes is no problem, since he is trying to redeem her and a relationship together.
In the other, the MC "only" tries to find a solution how to end the bloodletting on all sides as peacefully as can be done and here is where I see the problems. When the love routes cut off comes in this case, the MC is still comitted to the Hero path and has done no evil deeds (we can influence), has not sought revenge against e.g. Sondheim and kept contact with his team. So why should the love routes end there? The MC in this case wants to show SR a better way (which is obviously possible), end this war and return home to Kat (sharing/swinging or not). There might be an ending in the works that resolves this, but currently after chapter 16, there is a logic problem for cases like these.
