Bare
Raindrops pelted against the windowpane of Addison and Derek's home. No, what used to be the home of the Shepherd's. Now it was just an empty space, occupied by a ghost of a person. Derek had found out about her infidelity and left her, alone. At least she still had Mark, right? No he betrayed her too but he's still around. She doesn't know why she stays with him. Perhaps it's the fear of being alone. She doesn't want Mark, never did. She even tried to love him. She wants Derek, she needs him. But she has nothing left; her life packed up and left.
There are bags at the door and a sticky note on the fridge. She scribbled a good-bye note for Mark. She didn't have the guts to tell him in person. So just like that she left, trying to win back the love of her life.
