eric fields (emf) says: You know, that Cookie Jarvis is a magical bad-ass, considering he has the ability to speak to people telepathically, maintain a magic cloaking spell over a small army, and fly, and do battle with a psychotic leprechaun, all at the same time!

When Alfie said  "...Cookie Jarvis led us straight to you.", naturally I assumed he was referring to a telepathic conversation similar to the one between Jarvis and Tony on p 14.  But then it occurred to me, the same words might have meant the reinforcements found their way here by simply walking towards the unearthly fireworks display of orange stars, green clovers, purple horseshoes, etc, visible in the sky above, i.e. "[that crazy magic battle involving] Cookie Jarvis led us straight to you."  I mean a spectacle like that would be kinda hard to miss.
