What had happened is that when it saved we see that is she herself had changed a little because her age which was 30 just like Ben's was now 23, her breast have become bigger because they were now full of milk, she also has some stretch marks. Her cloth's had altered just a little because the shirt is now designed for breastfeeding.
Because reality had changed is that the place she's at is because she was meeting her mother there to look at the apartment so she could move out on her own.
