Hey guess what!? I play CoD more than Halo, but I'm not an annoying fanboy. I love CoD more, but I like how involved the Halo Community is...
Yeah but during the glimpse it is Daylight, meaning you are not the rookie. So my theory is this everyone woke up b4 the Rookie during someones flashback you come across this Drop pod and since its a few hours b4 the Rook wakes up , this Pod could be a fellow squad mate or just a dud, maybe someone is inside also unconscious so then they are awakened and taken with whoever found them.
