User blog comment:SouthParkClydeFan/Analysis on Lincoln's relationships with his sisters/@comment-28872366-20161003233320/@comment-24200891-20161004033302

The closest doesn't mean perfect. Luna is very close to Lincoln but sometimes he gives her reasons to be mad at him like in Making the Case or Ties that Bind. She herself had jerk moments in Sleuth and Consequences and It's a 7xLoud House. She loves him but it doesn't stop her from making fun of him. Still I like their relationship the most, I like it so much I often put it in my fanfics.
