I love how the Hargreeves don't give a sh*t for who their siblings love, like, "Vanya is in love with a farm woman with a husband and a son? Well good for her, hope she is happy. Klaus loves a soldier he met in Vietnam that doesn't even no him yet? Kinda sad but adorable bro. Diego is in love with the girl who just tried to kill their entire family? Whatever, hope it works out. Luther is in love with his sister? Well jokes will be made, but you do you man. Five is f*cking a mannequin? Literally the healthiest relationship, call us for the wedding."
Literally the only relationship anyone ever judged was Vanya and Leonard, and they were right.
