Talk:2401 Penitent Tangent

Theories
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. Even so, however, suggestions, and fans say that this, along with Guilty Spark, should play an important role when meeting even another monitor in Halo 3. Anyone who has played through Halo 2, and watched the cutscenes, saw that there were seven halos, and if the Bungie team makes another Halo game, there should be a time where all three monitors meet. However, this is purely speculation.

Questions
If Gravemind can use 2401 Pentitent Tangent to access all of Halo's systems, then why didn't he A. Lower the containment shield to infect the ring with flood? and B. Why did the sentinels on Delta Halo attack the flood?.
