Background

During the mission, Crowley was locked in a room full of feral ghouls by Dukov, who wanted to increase his own share of the pay. Crowley survived the imprisonment and harbors hatred toward those who left him behind.

Daily schedule
Mister Crowley can usually be found in either The Ninth Circle or in his bed at Carol's Place in Underworld.

Effects of player actions
Mister Crowley provides the Lone Wanderer with the You Gotta Shoot 'Em in the Head quest.

Behind the scenes

 * Mr. Crowley is possibly named after Aleister Crowley, a famous British writer and occultist. (Aleister Crowley's first name is often misspelled Alistair or Allistair, as in Allistair Tenpenny, the arch-nemesis of Underworld's Mr. Crowley.)
 * Mr. Crowley might also be a reference to an Ozzy Osborne song of the same name.

Bugs

 * Crowley may fall 'through' the Potomac River Bridge about two-thirds of the way across, probably due to a glitch in the programming. Crowley will continue his journey after his fall. (confirmed PC)
 * Occasionally, Crowley will go into a bout of slow motion sprinting, running at nearly half speed but with full striding animation. He will resume normal movement upon his next combat encounter. (confirmed PC, Xbox 360)
 * Crowley may deliver the "You stole what was rightfully mine!" line if the player acquires the Winterized T51b Power Armor from the Anchorage simulation. (confirmed PC, Xbox 360, PS3)
 * After getting the T51b Armor and Helmet from Fort Constantine by unlocking all the doors, then finishing the You Gotta Shoot Him In The Head quest by giving Crowley the keys, and fast traveling back to snatch the armor before Crowley finds out, Crowley has been encountered still friendly in the Presidential Metro, just inside the doors from M.A.R.Go.T., during the Who Dares Wins quest (BS and PL installed prior to beginning Crowley's quest, Steam version of game on PC).
 * Crowley may get stuck on his way to or from Fort Constantine. (confirmed 360)
 * Mister Crowley might rarely appear at your house still having all of the dialogue options as if he were still in the Underworld. After your encounter, he will walk back to the Underworld.
