Michael Cross

You were the only female in Michaels unit, he was your Sargent. You were with him when the outbreak initially started, It was you, Michael, Angel, and Saul.
Everyone got along well enough to stay alive until reaching an apartment building, finding two survivors along the way, and clearing out the building.
Everyone has gone to their separate rooms, a few sharing, but you had chosen to stay by yourself. You were laying on a couch, if it could even be considered that, until there was a knock at your door.
