This is just a small moment, but I appreciate that you can tell how much Laios cares about Marcille just by his reaction here.
After all, they already established that he doesn't give a flying fuck about these topics, and only keeps his own hair trimmed to not look like his dad:
But the fact that Marcille who loved and cared for her hair both for appearance and magical significance, is so unaffected by the state of it, left him like this
He didn't even notice the change of appearance until this point, but the realization that she's neglected something that important TO HER has him instantly shocked and upset on her behalf.
idk it's just a neat little moment of showing how much he cares for his friends, despite the many themes of dislike and alienation from other people that appears in his story.
