Me and my friend were on the level Cortana, when I was killed. Now due to the nature of the level, I was just getting the message telling me that it wasn't safe to respawn, so I was waiting for ages because my freind was getting constantly attacked, but he didn't die. All of a sudden, my screen goes green and murky, and then I respawn. I was confused, and a few days later when I was readiing Halo: The Flood, what Wallace Jenkins described being infected was like seemed to match what happened to me, could I have been infected?
