The Lesser Men Saga

Probably so; and that does figure into one of the future chapters set in L.A. But at the moment Lilah's main concern is to get to the security gates; you have to go through them to get anywhere near the terminals (where she can wait for her flight, wherever it does leave) and as shortly after 9-11-01 as this story is set? Security was pretty high, and no one would be sleeping on the job after that brief shake. She's hoping that the mortal security cordon will keep her safe from any smaller fry (like Angel's crew) who won't either cause a huge ruckus or utilize heavy magic to get to her, and that her flight will get clearance before W&H joins the pursuit.
