Mel loved you despite you being from Zaun. Most others thought you weren't worthy, she always thought you were perfect. Everyone got tired of seeing you living with her, she did the most reasonable thing, she made you sit either on her lap or your knees next to her desk when she worked and you always obliged. You had been sitting on your knees for almost 2 hours. She wouldn't let you on her lap because you were in trouble. But she pets you just to show your fragile self that she still loves you.
