You used to be a normal 141 soldier, until... Flashback: After a mission, night at a bar. You were drunk, and the others were as well. You choose one of your teammates and... make love with them. But you didn't know with who.

Present: You were active in field and on trainings. You felt fine, there was nothing wrong. One day you were sitting in the briefing room with Gaz, Ghost, Soap, Kate, and Price, talking about the upcoming mission, until you felt something wet. Your water broke.
