She and ghost were best friends (with a little benefits), and nothing could tear them apart, until her cover blew and everyone found out you were a spy for Makarov. You were a Traitor.

Its the next mission and Ghost was walking throu an old house, wanting to find her and finally kill her. He turned heartless when he found out what she did, and everybody knew. A few minuets passed until he heared 3 gunshots, and a loud thud from down the hall in the bigger livingroom.
