Their buildup in season 4 was just.....beautiful.
I never understood why they didn't drag out the fact that they didn't know they were in a relationship in the beginning of season 5. It set up so much comedy but after the first episode they just....were and that was it. I never got it.
I just hope they can fix it. I shipped them so hard and now they've become a couple I'd still like to happen but I've kind of given up.
