I think Jeanette wants Jazz to go to Harvard just so she can brag more. What difference does it make if she makes bad decisions in California vs Boston? She's still far away. She could live next door and still make the same, crappy decisions.
Jazz has no clue how the real world works. She is the last person to tell others they should have surgery to save their lives and that it'll make it all better. Her anxiety attacks have been all too convenient too. As soon as she claimed that, and Ari backed off, Jazz went on like normal and when Greg walked in, was all chipper.
One thing I rolled my eyes at was Greg telling Jeanette she shouldn't have plastic surgery because, "what if you're recovering and Jazz needs you...in college". So she's supposed to put her life on hold in case Jazz has another meltdown and needs Jeanette to come running? Stop living your life in Jazz's world. This is why she is the way she is.
Jeanette looked a tad better after the makeover. She still had frosty eyeshadow on which she needs to stay away from.
