This is where Grace Mukherjee lived. two other individuals may have also lived here with her based on some of the pictures she had in her house.
Morgan checks out the house Grace sent him to, where he finds radiation protection and pictures of Grace. Alicia radios him to tell him she found the kids but won't be able to get them back for the flight. Morgan looks out the window at a walker and sees himself in the reflection, telling Alicia they're going to get everyone out and do what they came to do.
