I've noticed that the WoL has different victory animations after certain dungeon bosses.

I just did Shadowbringers' Holminster Switch dungeon (great level) and due to
villagers being killed whilst fleeing, or likely turned into awakened bein...sorry sin eaters,
after the boss my character didn't do a jubilant victory pose but looked introspective/unhappy.

It's a good touch. I first noticed this after doing Tam Tara Deepcroft (hard). After
Edda falls off the edge with her robe set on fire and a smile on her face,
if my character did her jubilant female Miqo'te pose (where she stands on one leg with her hands together smiling) I probably would've burst out laughing at how out of touch and inappropriate it would've been. It's a small thing, but one that without care would've probably ruined what they were going for emotion-wise.
