In Season 3, Episode 11 "Birthday" Cordy is given the choice to rewrite history and live a different life had she not seen Angel in the first episode, leading to her having became a rich and famous actress. The reason she was given this choice was because Doyle wasn't meant to give the Visions to Cordy which would literally kill her (as we see another human with the back of her head having been exploded by one of her Visions).
After history is rewritten though Cordy is drawn to the Hyperion Hotel where Angel Investigations would have moved to and finds the writing on the wall in Angel's room she had written when she tried to possess Angel to direct him where to go to resolve the vision that caused her initial coma.
We know that the rewritten history should be free of anything relating to Cordy being in Angel Investigations because:
Fred was missing and one would assume to still be in Pylea as Angel, Gun and Wesley only went there to save Cordy who was sucked though the portal.
Gun and Wesley had Angel elsewhere and still turned up to slay the demon Cynthia summoned without Cordy's hint.
Yet she was drawn to the Hyperion Hotel to a hint that shouldn't exist. Does this mean the the Powers actually wanted Cordy to have the Visions anyway? If not then why did the Powers not correct at-least the hint Cody left behind in the original timeline?
