Mainly because it happens EVERY SINGLE TIME he’s not in a scene with the boys.
Can you ACTUALLY imagine KURT, knowing what he loves and what he most definitely DOES NOT, spending inordinate hours with Noah Puckerman cramming for an exam?
Has Kurt EVER become excited or thrilled about the prospect of being ‘one of the boys’?
Has Kurt ever CHOSEN the boys over the girls?
Has Kurt ever shown annoyance, sadness, disappointment or ANY sign that he feels left out of ‘bro’ moments?
Are Kurt’s closest friends the boys?
Has Kurt consistently chosen the girls and prefered the company?
Yes. Without fail.
Has Kurt shown disappointment and anger when he DOESN’T GET to be with the girls?
Yes. On more than one occassion.
Are Kurt’s closest friends some of the girls?
Yes. Namely, Rachel, Mercedes and Tina being his closest friends out of the whole school.
Have we seen Kurt seek out the girls for out of school activities thus showing he actively WANTS to spend time with them and ARRANGES it?
Yes. Sleepovers, prom prep etc.
Does Kurt share any interests that we know of with the boys?
Has Kurt shown any sign of being tiresome around the boys when they don’t appreciate his interests?
Does Kurt preferring to be with the girls and being teamed with them for their numbers/scenes make him any less of a boy?
No. It makes him human.
Is this list enough of a reason for Kurt to be included with the girls all of the time and not with the boys and their bro scenes…?
YES… coupled with the fact that Chris actively ASKED to be a part of the girl’s group because he feels Kurt prefers their company… I’d say an enormous YES.
