I agree with you.
She was my Durge's music teacher in this run (I helped her finish her song with my Tav). I read the trick to spare her and didn't do it because I wanted her death to be important for RP reasons. My Durge kept the music instrument she gave him during the whole run, as an important memento and a way to "keep her memory alive" with songs.
Also, the whole thing to spare her totally lack of sense.
On another note, I finally decided myself to finish Durge' story and.... Well, at least my team spoke during withers' speech (1 little line for each of them, I read that sometimes nobody speaks, was I super lucky ?) but that's it ^^' You're lying on the floor alone, which is super depressing (and unbelievable, sorry, especially with a love interest in your team).
And camp reactions after are unequals.
I'm glad I played this story (now, I know) but I'll stay on team Tav for my next runs.
