I'm just wondering how much the new epilogue would be involving best girl. Hell, it'd be nice if the epilogues takes into consideration whether u killed Raphael or not and if u did then player and Karlach could just go to the House of Hope and reunite with Hope and mayb see how well she is getting along with her sister (if u didnt kill her ofc) and seeing as how the way to get to the House of Hope is in a portal in the shop the dwarf woman runs it could make it easy for any of the companions who want to visit the player and Karlach and vice versa to come and go from and mayb if u didn't give the dwarf the gauntlets she asks u for she closes the portal cutting off access to the outside world for player and Karlach and if u give her the gauntlets she keeps the portal open (choices you make should have meaning after all)
(I doubt this would ever happen in the epilogue but hey, it makes sense in my headcanon)
also the patch needs to stop Wyll offering to take Karlach back to Avernus over the player if they want. If the player doesnt offer to go to Avernus with her THEN Wyll offers but I dont like Karlach romance dialogue being interrupted by the weak link of the party
the HoH would b the perfect place for the two to reside in it has bath's, big bed's, big-ass dinner table......and lots of demon bodies and a devil's......ah well, at least the rent would be non-existent
