I don't think it's the pairing's fault really. It's the fact that Glee has a really shitty group of writers (the new s3 ones especially) who don't know the meaning of fact-checking or character consistency. Because when Brittany's given the infantile treatment for the lulz, any sexual pairing with her is pretty terrible.

I'm actually really looking forward to this week's ep because from all the spoilers and leaked scenes that I've watched, it looks like a return to the s1!/Duets/Sexy/Rumors/Born This Way!Brittany that made most people ship and keep shipping Brittana in spite of all the other bullshit.
