2401 Penitent Tangent

2401 Penitent Tangent
2401 Penitent Tangent is the monitor of Installation 05, referred to by the humans as "Delta" Halo. Although it only shown briefly during the encounter with the Flood Gravemind deep in the bowels of Halo, 2401 Penitent Tangent is nearly identical to its brother monitor, 343 Guilty Spark, with the exception that it glows a dim red instead of bright blue. It speaks with the same upbeat, artifical voice that all monitors appear to have, and expresses excitement at the sight of the Master Chief, because "...a Reclaimer can activate the facility and contain this outbreak [of the Flood]". A short argument with a semi-deceased Prophet of Regret demonstrates that Penitent Tangent employs the same amount of regulation and protocol when it comes to dealing with the threat of the parasite. This is much to the discern of Regret, who insists that "...of all the objects [the Forerunners] left behind, there are none so worthless as these Oracles!" (The Oracle is the name given to the monitors by the Covenant)

Also revealed by Penitent Tangent is the fact that the ring(s) have been activated exactly once before, and is/are quite capable of being activated again. It shouts at Regret for the Covenant's blatant disregard of protocol in controlling the Flood. Before anything more can be said, 2401 Penitent Tangent is taken away.
