It's funny, back in season 3 I used to say that if Brittana breaks up, then I want Brittany with Sam, (or maybe Tina if her door happens to swing both ways,) they seemed to be a good match in theory, but the execution has just been terrible, and many steps backwards for both their characters.
I'm not sure that I want the promiscuous Santana back, even if it's with women and not with men like her first three years of high school, haha, but I don't mind if they give her one, or a couple of, steady relationships with someone who isn't Brittany. I want Brittana to get back together eventually, but not until they (or particularily Brittany) are more grown up.
