Favoritism and Effect on Siblings Relationship

Please stick with my thesis statement: The director uses the concept of parental favoritism in Fleabag to show the negative impact it has on the sibling relationships and the difficulties to overcome them.

Please use some evidence from the show to support the argument. Example; the funeral scene, dad telling Fleabag that he likes Claire more, Martin kissing Fleabag but Claire chose to believe Martin’s lies even though she knew the truth.
