PCPlaystation 3Xbox 360 Long after inviting you to meet with Caesar, he may appear, run up to the Courier, and initiate dialogue saying only "What do you need?" while your only option will be to end the conversation. This can even occur inside private hotel suites. (This can happen if you never met Caesar, or even if you have already killed Caesar). [verified]
When this occurs, Alerio may become permanently stationary at the Lucky 38 Hotel's entrance.
If he is killed when this occurs, he may respawn after a random amount of time.
