I think that jessiemeows was talking about
new evil ending, when as Embrace Durge you are forced to kill your love interest or let them escape

I also like Sceleritas a little bit. But let's not forget, that he may seem goofy but he is cruel projection of his master, god of murder.

But it's true that Sceleritas is more invested in our fight with Orin than our companions. That's another missing scene - Durge should be able to talk with companions and especially love interest just before the duel. They should comfort and support Durge in such important moment. And maybe it could be some type of goodbye with their partner - just in case things went wrong.
