If my niece came to me and put me in the position that she was putting her Aunt in, I can't say that I would want my niece to call me Uncle anymore. it showed a total lack of disrespect for Kayla, pushed her into a corner and threatened to put all the blame on Kayla and revoke the funding. Which probably is going to the same children's fund and doctors that helped Johnny with his eye surgery. Yup, I'd tell my niece where to stick and tell her to be on her way and to not come to me with anything.
I do think Sami has the right to be angry and hurt, even if she has done the same thing as EJ and she has because those feelings are real but no one went after her the way she is going after Abby, who is still telling everyone that what she did was wrong, when she cheated on Rafe.
