Seems like that's what they are implying. Little ridiculous ya. I'd be more willing to accept just a backup copy or something along those lines. You'd think the Ark would have backup copies of all of the monitors, so that it could replace both them and their ring if it became necessary. Maybe that's what they are implying instead? Not only was Spark destroyed, but he was in an interior room of Halo when it happened, not on the Ark.
