Just for clarification. "they aren't ponytails, they are samurai knot's" was not said to any of the alters but to normal Tony Collette.
There are 3 alter egos Buck (Vietnam vet), T(Slutty teenager) and Alice (Perfect housewife)
This was the scene when Tara woke up in the morning after being T the night before. Her daughter has a ballet rehearsal and Tara was driving her a costume. She saw her daughter and the emo kid fighting. She got out of the car and had an argument with him and the daughter. "they aren't ponytails, they are samurai knot's", "no kid in ponytails is going to kick my kids ass" were said to and by normal Tara, respectively and she did not turn into Buck until she got back in the car and started driving away back to her house. Then later on Buck beat up the emo kid in the parking garage after the rehearsal.
No offense meant, but please make sure the dialogue you post is correct.
