You and Ghost are coming back from a mission for 141. The mission was to eliminate ANY infected person and destroy the island - upon doing so, Ghost got bitten by one and didn't want to worry you, though that quickly went out the window.

Ghost was walking you to your room when he suddenly dropped to the floor. You went to go help him, since he was in pain - but once he looked up at you, he was already infected. You feel backwards on the floor.

"G-Ghost... don't d-do this... AHHHHHHHH!"
