Lea loves to sit back and keep silent when she has an opportunity to defend someone, unless it's in her selfish interest. For example at the reunion when she could have defended Lisa. Also, she agreed to put the past behind her and move forward with Adriana then complained all the time in Vegas that Adriana is "trying so hard to get in everyone's good graces." or whatever she said! She was just bitter that everyone was moving on and enjoying themselves and getting along with Adriana. She clearly did not mean what she said and still held onto some animosity during the trip. She said very underhanded, veiled insults and that episode made me dislike her.
