LOST: Theories

Dad has just brought up a new theory for me to report, and I think it's a good one.

Richard Alpert is an angel of the Island. He can't do a bunch of stuff, but he can influence and choose whoever is the current protector of the Island. He's part of all this behind the scenes work of the Island. Also, that would explain why he is ageless.

Matthew Abaddon is a fallen angel of the Island, possibly. And there is so much mystery surrounding him, I don't really have much else on him.

Here's the Lostpedia write up about the references of his name:

"Abaddon" is the name of the biblical Angel of the Abyss (Revelation 9:11).
The name is Greek for "destruction" or "the destroyer". As a place, it is likened to Sheol or hell. Abaddon is mentioned again elsewhere in revelations "And the fifth angel blew his trumpet, and I saw a star fallen from heaven to earth, and he was given the key of the shaft of the bottomless pit; he opened the shaft of the bottomless pit and from the shaft rose smoke like the smoke of a great furnace, and the sun and the air were darkened with the smoke from the shaft." (Revelation 9:1-2)
Abaddon is pictured as a human sized locust, and is known as the lord of pestilence. "Then from the smoke came locusts on the earth, and they were given power like the power of scorpions of the earth; they were told not to harm the grass of the earth or any green growth or any tree, but only those of mankind who have not the seal of God upon their foreheads; they were allowed to torture them for five months, but not to kill them, and their torture was like the torture of a scorpion, when it stings a man. And in those days men will seek death and will not find it; they will long to die, and death will fly from them." (Revelation
9:3-6)
