In every episode, Jessica fully shows her Asian-Tiger-Mother paranoid, making a complete mess, but in the end she will "realise" the importance of family, friendship or something bla bla, with the help of Louis or Honey. But in the next episode, things repeat again, she will not to learn from the past. I rarely see her change during the four seasons (I watch 4 seasons in 2 weeks), it is such a pity to make Jessica an unchanging figure. I had thought I would endure her character flaws. I didn't give up until epi 15 s4, just like an eruption of all my anger towards her.
