We didn't get a Faberry moment:Rachel constantly told Quinn she was better than she thought and she was more than just her looks. They were always there for each other, even when they "hated" one another.
We didn't get any Quartie scenes:Artie was one of the people who helped her through her accident and he's one of the reasons she was able to walk again so soon. He always believed in her.
We didn't get any Quinncedes scenes:They lived together for a while after Quinn couldn't stand living with Puck anymore. She cared about Quinn "Quinn chose Finn, and you need to accept that and move on ‘cause you have no business messing up that girl’s life any more than you already have" [to Puck]
We didn't get any Fabrevans scenes:He was the best boyfriend she had (IMO), he was respectful towards her and the only one who was faithful to her.
Even the Fuinn scene was all about Quick
So excuse us for being angry that our favourite character came back and all she did was interact with 2 people, and was thrown into this completely out of nowhere relationship whilst totally ignoring everyone who really cared about her.
