Mister Crowley

Mister Crowley is a resident of the Underworld who gives the player the "You Gotta Shoot 'Em in the Head" Quest. After completing this quest by giving the keys to Crowley, Crowley will proceed to Fort Constantine and may return to Underworld wearing the T-51b Power Armor. While he will also have the T-51b Power Helmet in his possession, he will not be wearing it.

Mister Crowley can usually be found in The Ninth Circle in the Underworld, although he rents a bed and sleeps at Carol's Place, also in Underworld.

Tasked by Allistair Tenpenny to retrieve a rare weapon, he along with five other mercenaries set off to accomplish this task. He was locked in a room full of feral ghouls by Dukov so the commission would not have to be shared. Crowley survived and harbors hatred to those who left him behind.

Crowley's journey
After you complete "You Gotta Shoot 'Em in the Head" by giving all the keys to Crowley, talk to him, and he'll say that he is preparing for a long trip. If you keep following him, you can see Mr. Crowley walk from the Underworld all the way to Fort Constantine. Several things to note here,
 * When following him, do not go past him when switching between instances. If you do so, he disappears. But if you enter an instance right after he does, he'll appear next to you and you can keep following him.
 * Crowley takes a rather LONG and circuitous route, basically following minor roads. Periodically he'll break away from the roads and then do a U-Turn coming right back to the same road he left, this should be noted for players intending to keep a distance.

His path is approximately as follows:
 * Into the Museum Station from Museum of History
 * Out of Anacostia Crossing
 * South to Rivet City Outskirts,
 * Northwest to Jefferson Memorial
 * Across the Potomac River,
 * North to the Citadel,
 * Then West towards the Nuka-Cola Factory,
 * And just past Andale,
 * North to Fairfax Ruins,
 * North by NorthWest to Jury Street Metro Station (It takes him approximately 13 game hours to reach this location from Underworld)
 * West through the Radpools on the southern board of Fort Bannister, engaging those Mercs on patrol.
 * North past Jalbert Brothers Waste Disposal, Everglow National Campground, and Rockbreaker's Last Gas, just short of Five Axles Rest Stop.
 * East past MDPL Mass Relay Station and through more Radpools which compose the partially dried Potomac. (Possibly wading through them.)
 * After reaching the nearest road while going eastbound from the Mass Relay station, he follows it northbound, just past Roosevelt Academy.
 * West by Northwest to Faded Pomp Estates
 * Here he travels North by Northeast through the estates and up a bush ridden dirt path just outside Relay Tower KX-B8-11 and onto the next adjacent road.
 * From here he travels along this road North all the way to Fort Constantine
 * Just as he leaves the road to head to the Fort, he goes hostile, attacking the player character if they get close, extreme distancing should be used in this situation, and it can be easy to lose track of him at night. What with the explosions from the Base's Sentries going off. If he actually assaults you any Brotherhood Outcasts in the Fort will attack him, as least if you're allied with them from scavving enough Tech.
 * He quickly ducks into the CO quarters back door against the rock face on the immediate left inside the base and proceeds to travel underground to the T-51b Armor Suit. (The Entire trip takes approximately 23 Game hours for Crowley who runs 90% as fast as a character with full agility, if for some reason you desired to actually beat him to it in a foot race, you'd win by hours.)
 * When Crowley enters the bomb storage door, it remains key locked, so you cannot continue along with him. If you wait for 3 hours in game and a few additional seconds Crowley will walk out of the same door, in his armor, no longer hostile to you. All doors will still be key locked if you desire to go inside after killing him.

Trivia

 * Mr. Crowley is possibly named after Aleister Crowley, a famous British writer and occultist, the subject of Ozzy Osbourne's 1980 single "Mister Crowley".
 * The quest "You Gotta Shoot 'Em in the Head" is most likely taken from Dawn of the Dead (2004) when a local zombie-slayer/cop was interviewed on how to kill zombies.
 * Aleister Crowley's first name is often misspelled Alistair or Allistair as in Allistair Tenpenny, the arch-nemesis of Underworld's Mr. Crowley.

Glitches

 * Sometimes, after unlocking all the doors, giving the keys to Crowley and taking the armor for yourself, Crowley will still stalk you but he will stay friendly. If he manages to appear inside your house, you can gain a room mate, since he will not try to exit the house and will stay on one place. Wadsworth will actually greet him "Good morning sir", even if the PC is female. You can still talk to him/pickpocket him, but if you want him out of your house, shoot him then go outside. He should follow you and you can kill him with no karma loss.
 * Occasionally, while crossing the Potomac River bridge, Crowley will fall 'through' the bridge about two-thirds of the way across, probably due to a glitch in the programming (PC). You can either choose to also fall through and swim after him or simply skirt the glitched bridge area and meet him on the other side.
 * Sometimes (If shot by the player, but not killed), Crowley will just stop moving. He will still appear hostile to the player, but will not attack them or any enemies in the area.
 * Occasionally Crowley will go into a bout of slow motion sprinting, where he runs at nearly half speed, but with full striding motion, ending upon his next combat encounter.
 * If Crowley starts his trek after completing the Waters of Life quest, he can sometimes get stuck in the water outside the Jefferson Memorial. He will swim up and down the river going nowhere. There seems to be no way to fix this.
