There was never a heart to heart talk between Stephanie and Michelle or Vicky
I could be mistaken but I don't ever remember there being a heart to heart talk between Michelle and Stephanie. They didn't really have the sisterly bond the way that D.J. and Stephanie had. Stephanie looked up to D.J. as her big sister. She was interested in what D.J. did in her life, read her diary and wore her clothes. She told D.J. how she wanted to be just like her when D.J. asked her why did she snoop through her things Stephanie said "You fascinate me. You go to school dances, you have 7 different teachers in the same day and you carry a purse. You're a woman of the world" Stephanie admired her whereas Michelle acted like an only child. You would have thought that Denise was Michelle's sister more than Stephanie because Michelle was around her friends more in the later seasons. Stephanie and D.J. sat down and had a heart to heart talk about how they felt especially in the later years like when Stephanie thought Steve was cheating on D.J. and she just wanted to protect her from getting hurt. The only time I can recall Michelle and Stephanie having a heart to heart talk is when Papouli died, Stephanie told Michelle to be brave for Uncle Jesse and think of something funny. Michelle never snooped through her things or wore her clothes. They just didn't seem like sisters. The same goes for Vicky she never really took the girls under her wing like Aunt Becky did. Aunt Becky showed D.J. how to apply make-up and talked to her about boys. Vicky was always on the go and running in and out of the house she barely spent time with the girls I mean for a woman who was engaged to their father she didn't seem.....motherly. Just an observation.
