I don't want Louis out of the picture so Blair can get with other guys. I want Louis out of the picture so that he can stop being so annoying, useless, and irritating. And so Blair can drop her delusional "fairytale" fantasies and focus on bettering herself and having better priorities. Blair doesn't love Louis.
The Blair-having-a-baby thing was pointless. Even Blair having a miscarriage still connects her to Louis in a special way knowing she was once pregnant with his baby. I hope the lab mixed up the results in some unbelievable tale just so Louis is completely gone from GG.
I too ship Blair/Blair.
