So what's the difference between an Angel and a Sentinel? Are Sentinels not Andro-Eidos like EVE? I thought Angels were called that because they come from the colony which is above Earth but where do sentinels come from then? Also there are a few people who claim to have siblings and we even meet a father/daughter pair, how does that work? Are they just programmed to act that way?
