Sometimes I think “wtf Julian is only 17 NO ONE in this shadowhunting world would be able to raise children at 17! Only him! Bc he strong and brave!” And then I remember that Charlotte Branwell had been head of the London Institute along with Henry since she was 18 years old and had to raise 3 children who weren’t even related to her, which included a bitter, spoiled girl; a sick boy; and a boy who was mean to every soul and was known to make Charlotte’s life a little impossible. And these kids didn’t feel any obligation to obey her, because she wasn’t family or even old enough.
So yes, Julian was brave and strong (especially because he had been raising his siblings by himself since he was TWELVE) but let us not forget Charlotte motherfucking Branwell.
