During season 5 episode, Tanks For The Memories , she was being brash and tactless, and a bit overprotective of Tank. By brash and tactless, I mean she was self-assertive and rude, and showing a lack of adroitness and sensitivity in dealing with others or with difficult issues.I get she cared for Tank, but she did more harm than good in that episode. Not only was that selfish, it was endangering her pet to boot. But she had to learn that nothing in life has to go your way, and you need to put your own needs aside for your friends.
What are your opinions on her development as a character in general?
