I was thinking and I realised that it does make sense that Quinn tried to pretend that nothing happened in season two. At first I was confused and annoyed that they weren't following up the beth storyline, but them I remembered somthing she said to her parents when they kicked her out "if you don't talk about it, it doesnt exist, so you just pushed it aside like we do every bad feeling in this house". Quinn had been raised to push things aside and not deal with them, and she was devestated when she found out she was pregnant and had to give up the picture perfect life she had created for herself after being very unhappy as "Lucy". Just when she felt happy and popular, she found out she was pregnant and everything changed for her. Then after she gave the baby up she wanted so badly to become the person she wanted to be again, and was very good at pretending nothing happened.Then Lauren decided to look into her past and discovered what Quinn had desperatly been trying to hide-her old life. This was the beggining of a downward spiral for her, she didn't become prom queen, which had been her dream throughout highschool, then on topo, início of it all Finn breaks up with her. I think somthing snapped and all the feelings she had been trying to pretend weren't there came out and she became very angry and hurt, which leads us to to the Quinn we are seeing now in season three, atuação out and furious. Then Shelbey comes back and brings up the memories of the baby she'd given up and the pain of giving birth to a beautiful baby girl and giving her to a stranger to raise. Now she is desperateto hold on to somthing that will make her feel good again:her daughter, which is why she is so desperate to see Beth and gain full custodey. I am not judgeing any of the characters in this summary and am just trying to show things from Quinns point of view, which will hopefully help other people understand why she's done what she's done and why she's atuação this way. Thank you for reading!
