Nooot as smart as you might think. :( Because this definitely happened and I know she's in the next two episodes as well. She should have just made a clean break.

If it makes Puck feel any better, she's sort of doing the same thing. She just hides it. What self-confidence she's managed to find though, is thanks in large part to him. He helped her grow up even when she didn't really want to.

Yeah, I know what you mean. I played her in a game for a while, but when the Glee cast faded away, she sort of did too. Now she mostly gets tossed up on memes, but with the writing of the show declining more and more every season, I think most people have pretty much jumped ship by now.
