Can Xoti reach +2 positive disposition/approval with Eder ?

[SenSx]

I really wish those two would be friends.

Eder isn't a fan of Xoti and her faith at the begining, but for some reason he managed to reach full +2 disposition with her, while Xoti who seems to be more interested in him than he is in her, his stuck at +1 for the whole game...

 

Is there a way to legit make her +2 with Eder or are there just no dialogues that allow to reach enough positive disposition for that ?

 

Thanks
