Hello im stuck with the end of the war.

I let thane die to get the scene with Seye. I defeated Axel, I talked to Nauxus at the lake giving him a positive answer about "getting to know each other better" and then I went with him to clean the temple and he gave me Axel's sword.

I went to talk to Nauxus again and nothing happens, plus I don't know where to find Seye. How do I get the scene with Nauxus and the Scene with Seye in this route? Please help :'(

You need to have done the quest to save Flo and opened the bathhouse. You can't get Selye's scene by losing to him in this route btw, it's only in the other ones, this has a bit of story unique to it later (more will come for sure) and potentially the best reward in a quest shared between the 4 routes later on, for now.
