I was busy with kids at the time,(so someone else might give a little more detail) but she came back from her trip and stopped by Jack and Carly's to give Carly a hard time for planting the compass in Julia's bag. Before she left she commented to Jack (Carly had left to rescue Lily who was trapped under the bed that Julia and Holden were getting cozy on) that she understood why Carly had it in for Julia, but not Lily. Jack basically told her to go home and talk to her son. I missed it exactly, but I think they were hugging/kissing/talking in Julia's room when Emma walked in. They had been talking about finding happiness and love (if I remember right). Emma started shouting about not finding it with her son! Then she yelled at Julia that she could stay the night, but be out of there the next day. Later, Emma was talking to Holden about his duty to his children and family. He started with the "I need to make myself happy" crap and how it was his life and he deserved to find happiness. She yelled at the top of her voice at him that it was his life, but it was HER house and she wanted Julia out. It was great to see Emma put her foot down.
