Okay, so Robert Lightwood has not been the best father in the history of the Shadowhunters. Not the worst (we all know that spot is saved for Valentine Morgenstern), but definitely not the best. He’s fucked up so many times that I probably couldn’t even try to recall them all. Julian is not even technically a father, but he does a better job at raising kids than Robert.
But this bit here in Lord of Shadows really touched my heart. While Robert has not always been the fairest to Alec, often blinded by his ignorance and fear, in his office hangs a tapestry where his son stands and fights in battle. You can tell from this moment he’s so fucking proud of his son, of his talent as a Shadowhunter. But he’s also proud of how he was willing to go into battle to protect those that he loves.
Robert was not a perfect father, but he was trying to be better and that’s character development and I fucking love it.
