1. It should have been more realistic if Glee has showed us some flash-back of Quinn's accident. Then her days in the hospital, she wakes up in a coma and got in a wheelchair.
2. Glee has forgotten to address if Finn and Rachel got married or not. They just assume, they didn't which leaves viewers confused.
3. Rachel, Santana, Brittany and Sam are Quinn's closest friends among the glee club. Faberry became close-friends. Brittana were also Quinn's cheerio and Sam became Quinn's close-friends in Rumours when she helped him baby-sit his siblings and their scene in Extra-oridinary Christmas.
When did Artie and Quinn had interaction in the past episodes? None. Not until now..
Lack of continuity
