Daeron is a Grantaire type of drunkard
If yk Les Mis yk(? Also this is concluded based on the TV show, so a large part of this impression could be from the writer, the director, the actor, and many others who has a say of how he's portraited on screen.
And ik ik, there's much difference between the two characters. Prince vs peasant, character serves different purpose in story, and the philosophy GRRM conducts in his writing couldn't be more different than Victor Hugo. Or if you want to be pedantic - he's way better looking than R and R knows way more sh*t than him.
But the depressed useless drunkard who is sarcastic and bitter, wallows in escapism and nihilism bc he has seen things and foreseen things, and knows his own uselessness too well to actually make a change (which is the vicious cycle of depression), but not exactly a bad person, only one that's self-destructive, that still cares about the people around him when he CAN. Lol I call this exact model of character design "the Grantaire type of drunkard".
And I love this type of character. They often have the least growth through out the story but has the potential of providing the most unexpected but deep philosophy or the struck-to-the-soul moment to the audience. I hope for some more appearance of the character, really, even though… I sense he's not exactly a big part of the story bc I noticed a kind of Machiavellianism from GRRM and he will more likely to use a small character like this for what he's worth instead of what he symbolizes, ie let him be a part of the rippling effect, mess things up then apologize by playing possum and rig his part of the match. LOL.
But hey, it's already refreshing to see a masochist among the oh-so-many sadist characters in the series LOL.
