I dont know where did you get that from but the manga disagree, she yelled that she is not going to save her tell more than anything you have written. The poke head is not even that meaningful, but the only Sasuke thing for her (may be for the rest of her life). She is still Sasuke wet fan until the very end of the manga.naruto cannot be a better parent to her than the one who raised her by herself and showed her love for many years. telling her good things about sasuke doesnt change that, dont be silly. even at times when sarada is down, she always calls out for her mom which shows how strong their bond is. sakura gave her a gesture(forehead poke) that is important to her dad which opened the way for it to be much more meaningful when sasuke does it to her aand when sasuke did indeed poke her forehead from her look we could tell she was very happy and understood what it meant, all courtesy of sakura. it put a smile on her face and she waved at sasuke happily. that>>whateva naruto told her about sasuke. you pple should quit the hate.
When you truly love some one you would have had the world for your lover. But Sakura destroy their home, Sasuke absent and not even showing what a father would do to the family in short amount of time with his family. Sarada would had abbadoned her family the moment she learned "the truth", if she had a good foster parent, she would never had those words toward them.
