2401 Penitent Tangent

"And you know nothing about containment! You have demonstrated a complete disregard for even the most basic protocols!"

- 2401 Penitent Tangent rebuking the Prophet of Regret

2401 Penitent Tangent is the Monitor of Installation 05.

Summary
Although only shown briefly during the encounter with the Gravemind deep in the bowels of Installation 05's Library, 2401 Penitent Tangent is obviously almost identical to its brother monitor, 343 Guilty Spark, with the exceptions that its voice is deeper than Guilty Spark's and its "eye" glows red instead of blue (although this could be because of Rampancy from interference by the gravemind). The holes on the side of 2401 Penitent Tangent are rectangular instead of round. He behaves much like 343 Guilty Spark does in his non-rampant state, and still shows regard for protocol.

According to a Forerunner artificial intelligence, Tangent neglected repairs of his Installation's Flood Containment Facility, resulting in several breaches by the xenoform and possibly the catastrophic outbreak that resulted in the organism's possession of the area around Installation 05's Library. There is a high chance that this Monitor was captured by the Gravemind while in combat as it is still in "combat mode" and glows dimly with its outer casing appearing to be damaged.

He is not encountered again after Master Chief meets him beneath the Library of Installation 05 (when he was captured is still uncertain), and he is not seen when Gravemind occupies High Charity. His fate following the Battle of Installation 05 is uncertain.

It is also possible that his default color is red, as he is seen humming to himself in a calm state on the Halo 2 map Backwash, yet he is still red.

Dialogue
(At the beginning the level Gravemind, 2401 Penitent Tangent is involved in a brief conversation with the Prophet of Regret.)

{Gravemind raises two tentacles, one wrapped around a red Monitor, the other merged with a half-Flood Prophet of Regret}

Monitor: "Greetings! I am 2401 Penitent Tangent. I am the Monitor of Installation 05."

Prophet of Regret: {Regret's voice is hoarse and he seems to have difficulty speaking} "And I am the Prophet of Regret, Councilor most high, Hierarch of the Covenant!"

{2401 Penitent Tangent sees the Master Chief.}

2401 Penitent Tangent: "A Reclaimer? Here? At last! We have much to do. This facility must be activated if we are to control this outbreak."

Prophet of Regret: "Stay where you are! Nothing can be done until my sermon is complete!"

2401 Penitent Tangent: "Not true. This installation has a successful utilization record of 1.2 trillion simulated and one actual. It is ready to fire on demand."

Prophet of Regret: (To the Arbiter) "Of all the objects our Lords left behind, there are none so worthless as these Oracles! They know nothing of the Great Journey!"

2401 Penitent Tangent: "And you know nothing about containment! You have demonstrated a complete disregard to even the most basic protocols!"

Gravemind: "This one's containment ... " {gives a disgusted huff} "And this one's 'Great Journey' are the same." {He lowers his tentacles, Regret shrieks in fear} "Your Prophets have promised you freedom from a doomed existence, but you will find no salvation on this ring. Those who built this place knew what they wrought. Do not mistake their intent, or all will perish as they did before ... "

Trivia

 * Penitent Tangent seems to be in a combat state while in the midst of the Gravemind (signaled by the red glow).


 * It is unknown why Penitent Tangent did/could not escape Gravemind, as Spark was shown to use a sort of force field to push objects and people away. Why Tangent did not use this is a mystery, though it is possible he was too damaged to use that function.
 * Some interesting facts are that 2401 Penitent Tangent's number is 343 Guilty Spark's number multiplied by 7, Bungie's famed favorite number. Also, 2401 is 74, or seven to the fourth power, and 2+4+0+1=7.
 * He is only seen briefly in a Halo 2 Campaign level Gravemind cutscene. He is also seen in the downloadable Halo 2 Multiplayer level Backwash.
 * The Gravemind may have only manipulated it just as 032 Mendicant Bias had been by the original Gravemind, because he still had intentions to activate Installation 05.
 * The Generator object on the Halo 3 map Orbital has the number 2401 on it.
 * 2401 Penitent Tangent was voiced by John Michael Higgins in Halo 2.
 * The amount of time passed in hours in the Cold Storage Transmission translates to:
 * Security Breach: 2512332 hours = approx. 286.6 years
 * Dereliction of Duty: 874068942 hours = approx. 99711.3 years with a margin of error of 61360 hours = approx. 7 years
 * "Penitent" refers to feeling or expressing sorrow for sin or wrongdoing and [being] disposed to atonement and amendment" and is synonymous with "repentant", and "tangent" is part of the idiom "off on a tangent", which refers to digressing suddenly from one course of action or thought and turning to another. This name may reflect the Monitor's current actions; it could be described as sorrowfully digressing from one course of action (neglecting its Installation) and turning to another (wishing to activate the Halo). This is interesting, as Penitent is a synonym for Guilty, and Tangent is similar to Spark. It has been theorized that all Monitors were named following this pattern.
