Elwën Berkeley's Links
Elwën has a lot of affection and gratitude for Léon.
Probably sees him as a father figure
Léon saved Elwën from a certain death when she was little. She then appeared again in his life and moved in his home. He sees her as a mix between a friend and a daughter.
She sees him as her little brother and would make everything in her power to be a good sister to Sirius (probably as a reaction to her shitty big brother ). She likes to affectionate pick on him but even more pick at other people with him.
The cool older sister he always dreamed of ! Feel like he can tell her everything and really appreciate her.
